Fig. 6 is a schematic diagram of a host system according to an exemplary embodiment of the present utility model.

In some alternative embodiments of the present utility model, host system 23 comprises: a processor 231 and a power manager 232.

In some alternative examples of the utility model, processor 231 is coupled to third terminal k3 and select terminal s1 of switch assembly 2222, respectively. The power manager 232 is coupled to the output of the power-on circuit 222.

In some alternative examples of the utility model, the power manager 232 is configured to: in response to receiving the power-on signal from the output of the power-on circuit 222, the control power supplies power to the host system 23 to enable the host system 23 to enter a startup procedure.

In some alternative examples of the utility model, processor 231 is configured to: in response to the processor 231 powering up, the switch assembly 2222 is controlled to be placed in the second state by the select terminal s1 of the switch assembly 2222. The processor 231 initializes the first controller 2211 to the interactive mode by resetting and communicates with the suction side device 30 through the first controller 2211.

In some alternative embodiments of the utility model, processor 231 may be represented as a CPU (Central Processing Unit ) and power manager 232 may be represented as a PMU (Power Management Unit, power manager). The processor 231 is used to run the startup procedure of each stage in the startup procedure. The power manager 232 is used for managing power and is responsible for controlling the power to supply power to each module in the electronic device 20 that needs to be powered. The power source may be a self-charging battery of the electronic device 20 or an external power source introduced by an ac adapter, and is not particularly limited.

The startup may be a startup, or a wake-up startup. The power-on start-up refers to the electronic device 20 starting up from the power-off state.

In some alternative embodiments of the present utility model, the power manager 232, upon receiving a signal from the power-on circuit 222, may compare to a threshold value (e.g., 0.7V, etc.) set in the power manager 232. If the voltage of the received signal is higher than the threshold value, the power manager 232 controls to supply power to the host system 23, so that the host system enters the start-up procedure.

In some alternative embodiments of the present utility model, after the host system 23 is powered, the processor 231 is powered up, and during the uboot phase, the processor 231 may control the operating state of the switch assembly 2222 to be placed in the second state through the selection terminal s1 of the switch assembly 2222, so that the processor 231 is turned on to the first controller 2211 through the switch assembly 2222, so that the processor 231 can communicate with the first controller 2211. Since the first controller 2211 is turned on to the second controller 2221 before, the first controller 2211 is reset and initialized by the second controller 2221, and the operation Mode is, for example, the CC Logic detection Mode or the Alt Mode interaction Mode of the Type-C interface, and the processor 231 cannot operate the first controller 2211. The processor 231 needs to reset and initialize the first controller 2211 again, so that the first controller 2211 is initialized to the interactive mode, so that the processor 231 can communicate with the sink device 30 through the first controller 2211, for example, acquire device information of the sink device 30 to determine whether the sink device 30 is a preset device, negotiate with the sink device 30 about power information required to be provided for the sink device, and the like.

It should be noted that the power-on circuit 222 shown in fig. 6 may be the power-on circuit 222 provided in any of the foregoing embodiments, for example, referring to any one of the power-on circuit 222 shown in fig. 4 and the power-on circuit 222 shown in fig. 5, only the switch component 2222 in the power-on circuit 222 is shown in fig. 6, and other portions may be referred to in fig. 4 and fig. 5.

In some alternative examples of the utility model, fig. 7 is a schematic diagram of an exemplary implementation of an electronic device provided by an exemplary embodiment of the utility model. The interface 21 is a Type-C interface, the first controller 2211 of the detection circuit 221 is a PD controller, and the second controller 2221 of the startup circuit 222 is an MCU. Since the Type-C interface includes two channel configuration pins of CC1 and CC2, transmission paths between the interface 21 and the switch assembly 2222, between the switch assembly 2222 and the MCU, and between the switch assembly 2222 and the CPU may be two-way. The switch assembly 2222 in the startup circuit 222 employs two paths of single pole double throw switches for conducting the CC1 and CC2 channels, respectively. The trigger component 2223 in the power-on circuit 222 is an or gate. PMU represents a power manager 232 in host system 23 and CPU represents a processor 231 in host system 23. VDD is a power supply terminal that provides an operating voltage. The MCU can monitor whether the host system is started up or not by monitoring the state of the GPIO port of the CPU. The CPU controls the switching of the operation state of the switch assembly 2222 through the GPIO port and the GPIO line. The I2C bus may include a two-channel bus of CC1 and CC 2.

The MCU performs reset initialization on the PD controller, and then the MCU sleeps. In the case that the sink device 30 accesses the Type-C interface, the PD controller may detect the access of the sink device 30, update its device access status to access, and send a trigger signal to the MCU (via a GPIO line between the PD controller and the MCU). The MCU wakes up from the sleep state upon receiving the trigger signal, and reads the device access state in the PD controller through the I2C bus between the MCU and the switch assembly 2222 and the I2C bus between the switch assembly 2222 and the PD controller. And responding to the access state of the equipment as access, and transmitting a second signal to the OR gate by the MCU. In response to receiving the second signal, the OR gate sends a power-on signal to the PMU. The PMU receives the starting signal and controls the power supply to supply power for the host system. The CPU is powered on, and controls the working state of the switch assembly 2222 to be placed in the second state (the first control signal may be sent through the GPIO line between the CPU and the selection terminal s1 of the switch assembly 2222), so as to conduct the CPU and the PD controller. The MCU enters a sleep state by monitoring the GPIO line between the CPU and the select terminal s1 of the switch assembly 2222, in case of hearing the first control signal. The CPU initializes the PD controller reset to the interactive mode and communicates with the sink device 30 via the PD controller. This is merely an exemplary embodiment, and in practical applications, the parts may be implemented in other ways. The first control signal may be a high level signal, and the high level signal may be, for example, 1V, 2V, 3V, 3.3V, 5V, or the like. The second control signal may be a low level signal, which may be, for example, 0V.

In some alternative embodiments of the utility model, processor 231 is further configured to:

the first controller 2211 acquires the device information of the suction end device 30, and determines whether the suction end device 30 is a preset device according to the device information. In response to the suction end device 30 being the preset device, the subsequent start-up procedure of the host system 23 is continued to be completed. In response to the suction terminal device 30 being not a preset device, the selector switch assembly 2222 is controlled to be placed in the first state by the selection terminal s1 of the selector switch assembly 2222, and the host system 23 is controlled to enter the shutdown procedure.

In some alternative embodiments of the present utility model, the device information of the sink device 30 may include information such as VID (VendorID, manufacturer ID) or PID (product ID) of the sink device 30, which may be specifically set according to actual requirements. The preset device can be set according to actual requirements. For example, the preset device may be a product of a preset manufacturer, a product of a preset product model, or the like. It is determined whether the sink device 30 is a preset device through the device information of the sink device 30. If it is determined that the suction end device 30 is the preset device, the processor 231 may continue to complete the subsequent startup procedure of the host system 23, which may be referred to as the foregoing, and will not be described herein.

In some alternative embodiments of the present utility model, if the suction side device 30 is not a preset device, the processor 231 may not continue to complete the subsequent startup procedure to control the host system 23 to enter the shutdown procedure in order to save resources. Before entering the shutdown procedure, in order to ensure that whether the suction end device 30 is connected to the interface 21 can be continuously detected, the processor 231 may control the switch assembly 2222 to be placed in the first state through the selection end s1 of the switch assembly 2222 (may send a second control signal to the selection end s1 of the switch assembly 2222), so that the first controller 2211 is turned on with the second controller 2221. After the control switch assembly 2222 is placed in the first state, the control host system 23 enters a shutdown procedure. The shutdown procedure returns the host system 23 to the state before entering the startup procedure. For example, before entering the startup procedure, the host system 23 is in a shutdown state, and the host system 23 is put into the shutdown state by the shutdown procedure. If the host system 23 is in a sleep state or a standby state before entering the startup procedure, the host system 23 is in a sleep state or a standby state after the shutdown procedure. And after the second controller 2221 monitors the second control signal sent by the processor 231 to the switch assembly 2222, the second controller 2221 wakes up and performs reset initialization on the first controller 2211, and then the second controller 2221 goes to sleep.

By acquiring the device information of the suction end device 30, the embodiment of the utility model can effectively judge whether the suction end device 30 is a preset device, and can continuously complete the subsequent starting process under the condition that the suction end device 30 is determined to be the preset device, so that further data interaction with the suction end device 30 or power supply for the suction end device can be performed. When it is determined that the suction end device 30 is not the preset device, the change-over switch assembly 2222 is placed in the first state, so that whether the suction end device 30 is connected to the interface 21 can be continuously detected, and the host system 23 is controlled to enter a closing process, so that a subsequent starting process is not performed, unnecessary electric quantity consumption can be effectively reduced, and self electric energy is saved.

In some alternative embodiments of the utility model, second controller 2221 is further configured to:

monitoring whether the host system 23 is started up; in response to monitoring that the host system 23 is powered on, the second controller 2221 enters a sleep state.

In some alternative embodiments of the present utility model, after the host system 23 enters the startup procedure, the second controller 2221 may monitor whether the host system 23 is started up, and the specific monitoring mode may be set according to the actual requirement. For example, the interception may be implemented by the interception processor 231 through the handover control signal of the handover switch element 2222, or may be implemented through other notification paths. The monitoring of the switching control of the switch assembly 2222 by the processor 231 may be implemented by monitoring the signal state of the selection terminal s1 of the switch assembly 2222. The second controller 2221 may consider that the host system 23 is powered on to be completed in the case where the first control signal is monitored, and the second controller 2221 enters a sleep state.

In the embodiment of the present utility model, the second controller 2221 enters the sleep state after monitoring that the host system 23 is started, so that the consumption of electric energy can be further reduced, and the standby time of the battery of the electronic device 20 can be prolonged.

In response to the device access status being access, device information of the suction side device 30 is acquired through the first controller 2211. Whether the suction side device 30 is a preset device or not is determined according to the device information. In response to the suction end device 30 being a preset device, a power-on signal is sent to the host system 23 through the first end c21 of the second controller 2221. In response to the suction side device 30 being not a preset device, the second controller 2221 enters a sleep state.

In some alternative embodiments of the present utility model, the first controller 2211 may be reset initialized to the interactive mode by the second controller 2221 to enable the second controller 2221 to communicate with the suction side device 30. In the case where the switch assembly 2222 is placed in the first state and the second controller 2221 receives the trigger signal through the second terminal c22, the device access state in the first controller 2211 may be read. In the case that the device access state is determined to be access, the second controller 2221 may communicate with the first controller 2211 by switching the conduction path between the switch component 2222 and the first controller 2211, so as to obtain the device information of the suction end device 30 through the first controller 2211. If it is determined that the suction end device 30 is a preset device, the second controller 2221 sends a power-on signal to the host system 23 through the first end c 21. If it is determined that the suction end device 30 is not the preset device, the second controller 2221 enters the sleep state and does not send the power-on signal to the host system 23, so as to determine whether the suction end device 30 is the preset device before sending the power-on signal, thereby avoiding the host system from entering the start-up procedure by mistake and further reducing the consumption of electric energy. And when the suction terminal device 30 is not a preset device, the second controller 2221 enters a sleep state, so that the power consumption can be further reduced.

Fig. 10 is a schematic structural view of an electronic device according to still another exemplary embodiment of the present utility model.

In some alternative embodiments of the present utility model, the switching circuit 223 includes: a switch assembly 2231 and a resistor 2232.

A first terminal r1 of the resistor 2232, a third terminal t3 of the switch assembly 2231, and an input terminal ei of the power-on circuit 224 are coupled via a common node m. A second terminal r2 of the resistor 2232 is coupled to the power terminal VDD, which provides the operating voltage. The first state is that the first terminal t1 and the third terminal t3 of the switch assembly 2231 are turned on, and the second state is that the first terminal t1 and the second terminal t2 of the switch assembly 2231 are turned on.

In some alternative embodiments of the present utility model, the specific structure and working principle of the switch assembly 2231 can be referred to the switch assembly 2222 of the foregoing embodiment, which is not described herein. The change-over switch assembly 2222 of the foregoing embodiment is different from the connection relation with other components and functions in the power-on control module 22. In order to distinguish between descriptions of the switch assembly 2222 and the switch assembly 2231, the switch assembly 2222 may be referred to as a first switch assembly 2222 and the switch assembly 2231 may be referred to as a second switch assembly 2231.

In some alternative embodiments of the present utility model, the interface 21 is in conduction with the power-on circuit 224 with the first terminal t1 and the third terminal t3 of the switch assembly 2231 being in conduction, so that the power-on circuit 224 can send a power-on signal to the host system 23 in response to the interface 21 accessing the sink device 30. With the first and second ends t1, t2 of the switch assembly 2231 conductive, the interface 21 is conductive with the host system 23 to enable the host system 23 to communicate with the connected sink device 30 via the interface 21.

Without the sink device 30 accessing the interface 21, the voltage at the common node m is equal to the operating voltage of the power supply terminal VDD. In the case where the first terminal t1 and the third terminal t2 of the switch assembly 2231 are conductive and the sink device 30 is connected to the interface 21, the voltage at the common node m is pulled low. Such that the voltage at the input ei of the power-on circuit 224 is equal to or approximately equal to the voltage at the pin of the interface 21, such as the voltage at the pin of the Type-C interface CC, the power-on circuit 224 is able to detect a change in the voltage state of the pin of the interface 21 in the event that the interface 21 is connected to the sink device 30, and in response thereto, send a power-on signal to the host system 23.

In some alternative embodiments of the present utility model, the connection between the interface 21 and the power-on circuit 224 and the host system 23 may be implemented through one or more channels according to the type of the interface 21.

For example, the diverter switch assembly 2231 may employ a two-way single pole double throw switch or other switch assembly to effect conduction of two transmission channels, the resistor 2232 may include two resistors, and so on.

According to the embodiment of the utility model, through switching the switch component and the resistor, when the suction end equipment is connected to the interface, the voltage of the input end of the starting circuit and the voltage of the relevant pin of the interface 21 have synchronous changes, so that the starting circuit is triggered to send a starting signal to the host system, and the suction end equipment is connected to the automatic control host system to enter a starting process.

The first input of the comparing component is used as the input ei of the power-on circuit, and the second input pi2 of the comparing component 2241 is used for coupling with the reference voltage Vref.

In the case that the interface 21 is not connected to the sink device, the voltage of the first input pi1 of the comparing component 2241 is higher than or equal to the reference voltage, so that the comparing component 2241 cannot transmit the power-on signal to the host system 23.

For example, for a Type-C interface, the comparison component 2241 may include two comparators for comparing the voltage corresponding to the CC1 pin with the reference voltage and comparing the voltage corresponding to the CC2 pin with the reference voltage, respectively. For the Type-C interface, if the diverter switch assembly 2231 employs a two-way single-pole double-throw switch, the moving ends of the two-way single-pole double-throw switch of the diverter switch assembly 2231 can be electrically connected to obtain the third end t3 of the diverter switch assembly, so that the resistor 2232 can include a resistor and the comparing assembly 2241 can include a comparator.

According to the embodiment of the utility model, the voltage of the common node is compared with the reference voltage through the comparison component to determine whether to send the starting signal to the host system, so that accurate and effective triggering of the operation of sending the starting signal is realized.

In some alternative examples of the utility model, fig. 14 is a schematic diagram of another exemplary implementation of an electronic device provided by an exemplary embodiment of the utility model. In this example, the interface 21 is a Type-C interface, the switch assembly 2231 in the switch circuit 223 is a two-way single pole double throw switch, and the switch circuit 223 further includes two resistors 2232 (i.e., rp). The comparing component 2241 in the power-on circuit 224 includes two comparators C, and the triggering component 2242 in the power-on circuit 224 is an or gate. Controller 233 in host system 23 employs PD control, PMU represents power manager 232 in host system 23, and cpu represents processor 231 in host system 23. I2c_sda denotes a data signal line of the I2C bus, i2c_scl denotes a serial clock line of the I2C bus, and INTn denotes an interrupt signal line.

Since the two paths of single-pole double-throw switches respectively conduct CC1 and CC2 of the interface 21 with the two resistors Rp, in the case that the suction terminal device 30 is connected through the Type-C interface, one CC pin of the interface 21 is pulled down to a low level, so that one of the two comparators C outputs a high level pulse (i.e., a first signal) to the or gate. The output of the OR gate sends a high power-on signal to the PMU. The PMU receives the starting signal and controls the power supply to supply power for the host system so that the host system enters a starting process. After the CPU is powered on, the two-way single-pole double-throw switch is placed in the second state by controlling the select terminal (i.e. s 2) of the two-way single-pole double-throw switch through the GPIO line (which may send the first control signal) to couple the interface 21 to the PD controller. The CPU initializes the PD controller reset to the interactive mode and communicates with the sink device 30 via the PD controller. The present utility model is merely an exemplary embodiment, and the components may be implemented in other manners in practical applications.

In some alternative embodiments of the utility model, the current battery charge may be implemented using any practicable charge measurement. Such as measuring battery voltage, etc. The preset power may be set according to the power required for normal operation of the electronic device 20 after the electronic device is started. If the host system 23 receives the power-on signal, it determines that the current battery power is greater than or equal to the preset power, then the start-up procedure is entered. Otherwise, the host system 23 may enter the off state to avoid the situation that the power is too low to start or the power cannot work normally after starting.

In some alternative embodiments of the present utility model, the power manager 232 in the host system 23 obtains the current battery power upon receiving the power-on signal, and does not perform the subsequent operation of controlling the power supply to supply power to the host system 23 in response to the current battery power being less than the preset power. In response to the current battery power being greater than or equal to the preset power, the power manager 232 controls the power source to supply power to the host system 23 to cause the host system to enter a startup procedure.

In response to receiving the startup signal, the host system in the embodiment of the utility model enters a startup process under the condition that the current battery power is determined to be greater than or equal to the preset power, so that the battery power can support the startup of the host system and can normally work after the startup, thereby improving the startup effectiveness and avoiding the occurrence of invalid startup conditions such as incapability of normal startup due to too low power and incapability of normal work after the startup.
