Description

Technical Field

Background
Universal Serial Bus (USB) is a Serial port Bus standard for connecting a host and a peripheral device, and is also a technical specification of an input/output interface, and is widely applied to information communication products such as a host and a peripheral device, and is extended to other related fields such as video equipment, digital televisions (set-top boxes), game machines, and the like.
USB includes several specifications, such as USB 2.0 and USB 3.0, wherein the maximum current limit provided by USB 2.0 is 500mA, and the maximum current limit provided by USB 3.0 is 900 mA. The conventional peripheral device supporting the USB specification cannot determine that the connection port of the host supports USB 2.0 or 3.0, and the peripheral device is limited to receive a smaller current of 500mA due to safety considerations. However, when the host connected to the peripheral device supports USB 3.0, the peripheral device still limits the current to receive only 500mA, which limits the application of the peripheral device.
Therefore, those skilled in the art have considered it necessary to develop a peripheral device capable of determining the specification supported by the host.

Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
the invention is described in detail below with reference to the drawings and specific examples, but the invention is not limited thereto.
Referring to fig. 1 and 2, a schematic diagram of an electronic device system 100 according to an embodiment of the invention is shown, and fig. 2 is a functional block diagram of the electronic device system 100 of fig. 1. The electronic device system 100 includes a peripheral element 110, a peripheral device 120, and a host 130. The peripheral device 110 supports the Universal Serial Bus (USB) specification.
As shown in fig. 2, the peripheral device 110 may include a first pin 111, a second pin 112, a third pin 113, a first resistive element 114, and a second resistive element 115. The second pin 112 supports the first USB specification, but does not support the second USB specification. The first resistor element 114 is electrically coupled to the first pin 111 and the third pin 113. The second resistor element 115 is electrically coupled to the second pin 112 and the third pin 113. Thus, when the peripheral device 110 is electrically coupled to the host 130 and the peripheral device 120, the peripheral device 120 can determine that the specification supported by the host 110 is the first USB specification or the second USB specification according to the voltage value of the third pin 113.
In one embodiment, the first pin 111 is, for example, a supply voltage pin, the second pin 112 is, for example, a reference pin, and the third pin 113 is, for example, a cc (configuration) pin. The "CC pin" herein is a predetermined pin of the USB specification. For example, the second pin 112 is, for example, a ground pin of USB 3.0, such as pin No. 7 (pin 7).
In the present embodiment, the peripheral element 110 and the peripheral device 120 are detachably coupled. For example, the peripheral device 110 is a transmission line that mechanically (e.g., interposes) electrically couples the peripheral device 120 and the host 130. In detail, the peripheral device 110 includes a first connection port 110A, a second connection port 110B and a connection line 110C, wherein the connection line 110C connects the first connection port 110A and the second connection port 110B. The first pin 111, the second pin 112, the third pin 113, the first resistive element 114 and the second resistive element 115 may be disposed on the second connection port 110B, for example, but according to different product size designs or use requirements, one skilled in the art can adaptively adjust at least one, more or all of the first pin 111, the second pin 112, the third pin 113, the first resistive element 114 and the second resistive element 115 to be disposed on the first connection port 110A, which is not intended to limit the scope of the embodiment of the invention.
The peripheral device 110 is coupled to the host connection port 130A of the host 130 via the first connection port 110A, and coupled to the device connection port 120A of the peripheral device 120 via the second connection port 110B, such that current (power) and/or data can be transmitted between the host 130 and the peripheral device 120 via the peripheral device 110. In one embodiment, the first connection data 110A is, for example, a connector supporting USB Type A (USB Type-A) specification, and the second connection data 110B is, for example, a connector supporting USBC Type (USB Type-C) specification. The host connection data 130A supports one of a first USB specification, such as USB 3.0, and a second USB specification, such as USB 2.0.
In another embodiment, the peripheral element 110 can also be integrated into the peripheral device 120. For example, the peripheral element 110 and the peripheral device 120 are integrated into another peripheral element. In this example, the peripheral element 110 is not detachable from the peripheral device 120. In other embodiments, the peripheral element 110 may be integrated with the host 130.
In one embodiment, the peripheral device 120 is an electronic device suitable for the host 130, such as a mobile power supply, a mobile hard disk, an input/output device (e.g., a keyboard or a mouse), a speaker (e.g., a headset), an audio/video player, or a communication device. The host 130 is various electronic devices having specific functions, such as a desktop computer, a notebook computer, a tablet computer, and a home appliance. As shown in fig. 2, the peripheral device 120 includes a fourth pin 121, a ground potential 122, a controller 123 and a third resistor element 124, wherein the third resistor element 124 is electrically coupled to the ground potential 122 and the fourth pin 121. The fourth pin 121 is, for example, a CC pin. In addition, the fourth pin 121, the ground potential 122, the third resistive element 124, etc. can be regarded as simplified circuits of the peripheral device 120, and are coupled to the second connection port 110B of the peripheral device 110 through the device connection port 120A.
As shown in fig. 2, when the peripheral device 110 is coupled to the peripheral device 120, the third pin 113 is electrically connected to the fourth pin 121, and the third pin 113 and the fourth pin 121 are at the same potential. Although not shown, the first pin 111 and the second pin 112 of the peripheral device 110 are electrically connected to corresponding pins (not shown) of the peripheral device 120, and the first pin 111 and the second pin 112 are also electrically connected to corresponding pins (not shown) of the host connection port 130A of the host 130.
Since the second pin 112 supports the first USB specification, but does not support the second USB specification. Therefore, when the host port 130A of the host 130 supports the first USB specification, after the peripheral device 110 is coupled to the host 130 and the peripheral device 120, the second pin 112 can be electrically coupled to the corresponding pin of the host port 130A of the host 130; when the host port 130A of the host 130 supports the second USB specification, after the peripheral device 110 is coupled to the host 130 and the peripheral device 120, the second pin 112 floats on the host port 130A of the host 130 because the second pin 112 does not support the second USB specification.
Since the second pin 112 has different coupling states (electrically coupled or floating) for different USB specifications, the third pin 113 correspondingly generates different pin voltages (CC pin voltage) V for different USB specificationsCThe peripheral device 120 may read the value according to the pin voltage VCDetermines the USB specification supported by the host connection port 130A of the host 130.
For the host connection port 130A of the host 130 supporting the second USB specification, after the peripheral device 110 is coupled to the peripheral device 120 and the host 130, the second pin 112 floats over the host connection port 130A of the host 130 (the second resistor 115 is not a component on the loop). In this case, the pin voltage VCCan be obtained according to the following formula (a).
For the host connection port 130A of the host 130 supporting the first USB specification, when the host 130 is connected to the peripheral device 110, the second pin 112 is electrically coupled to the host connection port 130A of the host 130 (the second pin is electrically coupled to the host connection port 130A of the host 130)Resistive element 115 is an element on the loop). In this case, the pin voltage VCCan be obtained according to the following formula (b).
V in the formulae (a) and (b)SRepresents the host supply voltage of the first pin 111, and VCThe pin voltage of the third pin 113, R1 is the first resistance of the first resistive element 114, R2 is the second resistance of the second resistive element 115, and R3 is the third resistance of the third resistive element 124.
VC＝(VS/(R1+R3))×R3................................(a)
VC＝(VS/(R1+R2//R3))×(R2//R3)..........(b)
Due to the pin voltage V of the third pin 113CAnd the pin voltage (CC pin voltage) V of the fourth pin 121CIn the equipotential situation, the controller 123 of the peripheral device 120 can be driven according to the pin voltage V of the fourth pin 121CThe pin voltage V of the third pin 113CEither determines the USB specification supported by the host connection port 130A of the host 130.
In an embodiment, the controller 123 is configured to: (1) detecting the pin voltage V of the fourth pin 121C(or the pin voltage V of the third pin 113C) (ii) a (2) Determining the pin voltage VC(or the pin voltage V of the third pin 113C) Whether the first judgment voltage is equal to the first judgment voltage or the second judgment voltage; (3) when the pin voltage VC(or the pin voltage V of the third pin 113C) Equal to the first judgment voltage, receiving a first supply current; (4) when the pin voltage VC (or the pin voltage V of the third pin 113)C) Equal to the second determination voltage, and receives a second supply current.
The maximum limiting current provided by the first USB specification and the second USB specification are different. For example, the maximum limiting current provided by the first USB specification is, for example, 900mA for USB 3.0, and the maximum limiting current provided by the second USB specification is 500mA for USB 2.0. When the controller 123 of the peripheral device 120 determines that the specification supported by the host connection port 130A of the host 110 is USB 2.0, the peripheral device 120 receives a current (a second supply current) of 500mA provided by the host 110; when the peripheral device 120 determines that the specification supported by the host connection port 130A of the host 110 is USB 3.0, the peripheral device 120 receives a larger 900mA current (the first power supply current) provided by the host 110, so that the peripheral device 120 can obtain a larger current.
To sum up, one of the determination methods for peripheral devices supporting the usb type-C specification according to the embodiments of the present invention includes: (1) determining a first determination voltage and a second determination voltage, wherein the first determination voltage and the second determination voltage are obtained according to at least one lookup table, for example; and (2) when the peripheral element is electrically coupled with the peripheral device and the host, the peripheral device determines that the host supports a first universal serial bus specification or a second universal serial bus specification by referring to the first judgment voltage and the second judgment voltage.
A method of determining the first resistance value R1 of the first resistance element 114 and the second resistance value R2 of the second resistance element 115 (a method of manufacturing peripheral elements) will be described below.
In one embodiment, the method for fabricating the peripheral device 110 includes: (1) determining a first judgment voltage and a second judgment voltage; (2) determining a first resistance R1 of the first resistance element 114 according to the second determination voltage; (3) the second resistance R2 of the second resistor element 115 is determined according to the first determination voltage and the first resistance R1. Specifically, the method for manufacturing the peripheral element 110 includes: (1) determining a first judgment voltage and a second judgment voltage; (2) according to the second judgment voltage and the host supply voltage VSAnd the third resistance R3 of the third resistive element 124, which determines the first resistance R1 of the first resistive element 114; (3) according to the first judgment voltage and the host supply voltage VSThe third resistance value 124 and the first resistance value R1 determine the second resistance value R2 of the second resistance element 115.
In particular, in determining the host supply voltage VSAfter the values of the third resistance R3, the first determination voltage, and the second determination voltage of the third resistor 124, the first resistance R1 of the first resistor 114 can be calculated (or determined) according to the above formula (a), and the second resistance R2 of the second resistor 115 can be calculated (or determined) according to the above formula (b). Pin of formula (a)Pressure VCSubstituting the second judgment voltage into the pin voltage V of the formula (b)CSubstituting the first judgment voltage. In the order of the expressions (a) and (b), the first resistance R1 of the first resistance element 114 can be determined by the expression (a), and then the second resistance R2 of the second resistance element 115 can be determined by the expression (b).
Illustrated with specific values, as shown in Table 1 below, the host supply voltage V at the host 130SUnder the conditions of 5 volts (V), 5.1K Ω of the third resistance R3 of the third resistive element 124 of the peripheral device 120, 2.5V of the first determination voltage, and 3.1V of the second determination voltage, the first resistance R1 of the first resistive element 114 is calculated to be 3.1K Ω by using the above formula (a); then, the first resistance value R1 is substituted into the above equation (b), and the second resistance value R2 of the second resistance element 115 is calculated to be 7.91K Ω. The first resistance value R1 of the first resistance element 114 is smaller than the second resistance value R2 of the second resistance element 115. However, depending on the values of the third resistance R3, the first determination voltage and the second determination voltage of the third resistive element 124, the first resistance R1 of the first resistive element 114 may be greater than the second resistance R2 of the second resistive element 115.
TABLE 1
Figure BDA0002506418230000071
As another example, as shown in Table 2 below, the host supply voltage V at the host 130SUnder the conditions that the third resistance value R3 of the third resistive element 124 of the peripheral device 120 is 5.1K Ω at 5V, the first determination voltage is 3V, and the second determination voltage is 4.5V, the first resistance value R1 of the first resistive element 114 is calculated to be 566 Ω by using the above formula (a); then, the first resistance value R1 is substituted into the above formula (b), and the second resistance value R2 of the second resistance element 115 is calculated to be 1.02K Ω. The first resistance value R1 of the first resistance element 114 is smaller than the second resistance value R2 of the second resistance element 115. However, depending on the values of the third resistance R3, the first determination voltage and the second determination voltage of the third resistor element 124, the first resistance R1 of the first resistor element 114 may be greater than the second resistor element 115And a second resistance value R2.
TABLE 2
Figure BDA0002506418230000072
In another embodiment, the host supply voltage VSAnd may be a 3.3V or other specification supply voltage. Different main machine supply voltage VSThe first resistance R1 of the first resistive element 114 and the second resistance R2 of the second resistive element 115 can be obtained differently.
In an embodiment, the first determination voltage is different from the second determination voltage. For example, as shown in table 1, the value 3.1 of the second determination voltage is different from the value 2.5 of the first determination voltage, and as shown in table 2, the value 4.5 of the second determination voltage is different from the value 3 of the first determination voltage. Thus, by using different determination voltages, the controller 123 can be prevented from misdetermining the USB specification supported by the host connection port 130A of the host 110.
In addition, under consideration of the error, the error range of the first determination voltage is completely staggered with the error range of the second determination voltage, i.e., completely non-overlapping. For example, under consideration of voltage error, such as about 10%, the error range of the first determination voltage is between 2.9V and 3.3V, and the error range of the second determination voltage is between 2.4V and 2.8V. Even if the voltage error is considered, the error range of the first judgment voltage and the error range of the second judgment voltage are still completely staggered, namely, the first judgment voltage and the second judgment voltage are still not overlapped. Thus, by completely staggering the determination voltage ranges, the controller 123 can be prevented from misdetermining the USB specification supported by the host connection port 130A of the host 110. In another embodiment, the voltage error may be less than or greater than 10%, and the embodiment of the present invention does not limit the actual value of the voltage error.
In addition, the first judgment voltage and the second judgment voltage are interval values outside the pin voltage specification established by the USB Type-C. For example, the predetermined pin voltage specification for USB Type-C includes a range of 0.25V to 0.61V, a range of 0.7V to 1.16V, and a range of 1.31V to 2.04V. As long as the first determination voltage and the second determination voltage are completely staggered from the predetermined pin voltage specifications, the embodiments of the present invention do not limit the specific values and/or ranges of the first determination voltage and the second determination voltage. In another embodiment, a memory unit (not shown) of the host 130 may include a plurality of lookup tables (e.g., tables 1-2), and define a voltage range for each of the first determination voltage/the second determination voltage, for example, the voltage range defined in table 1 (the first determination voltage is 2.4-2.8V, the second determination voltage is 2.9-3.3V) or the voltage range defined in table 2 (the first determination voltage is 2.5-3.5V, the second determination voltage is 4.05-4.95V), so that when the peripheral device 120 is electrically coupled to the host 130 via the peripheral device 110, the host 130 may correspondingly determine the appropriate voltage range (or the corresponding lookup table), and simultaneously determine the first USB specification (e.g., USB 3.0) or the second USB specification (e.g., USB 2.0) supported by the peripheral device 120, so as to supply power to the host 130 or electrically control the peripheral device 120.
In another embodiment, referring to the types of the peripheral device 120 and the host 130, those skilled in the art can suitably integrate the peripheral device 110 into the peripheral device 120 or the host 130, or refer to the connection manner among the peripheral device 110, the peripheral device 120 and the host 130, and those skilled in the art can also arrange the first pin 111, the second pin 112, the third pin 113, the first resistor 114 and the second resistor 115, etc. in the circuit electrically coupling the first connection port 110A and the host connection port 130 to each other (or in the circuit electrically coupling the second connection port 110B and the device connection port 120A to each other), which also falls into one of the scope of the present invention.
In summary, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
