Fig. 3 is that as shown in Figure 3, the method, for mobile terminal, is provided with in this mobile terminal for carrying out protection IC and the MOSFET of overcurrent protection according to a kind of process flow diagram of controlling the method for battery and main equipment disconnection shown in an example embodiments.Wherein, mobile terminal includes but not limited to mobile phone, panel computer etc., and the present embodiment is not done concrete restriction to mobile terminal.The method flow that disclosure embodiment provides comprises the following steps.
In step 301, under open state, obtain shutdown indicator signal, and generate shutdown command according to shutdown indicator signal.
Generally, mobile terminal has two states: open state and off-mode.Battery under open state in mobile terminal is powered to the main equipment of mobile terminal by the circuit being connected with main equipment, so that mobile terminal is in running order.The electric energy that descends in working order mobile terminal to utilize battery to supply with not only can start some application programs, as, game class application, the application of shopping class, the application of Life Guidance class etc., and can carry out some function, as, receive and send messages, play telephone crosstalk, photograph, shooting etc.And the battery in mobile terminal and the circuit between main equipment are in off state under off-mode, battery cannot be powered to main equipment, and now mobile terminal will quit work, and the electric energy in battery can not be consumed yet.
Conventionally mobile terminal in working order under along with the application program starting or the function of execution increase, the electric energy consuming is also more, and the electric energy that battery in mobile terminal is stored is limited, and because mobile terminal electric energy in battery when the off-mode can not be consumed, therefore, for saves energy, when working without mobile terminal, can make mobile terminal change off-mode into by open state.And mobile terminal changes off-mode into by open state, the shutdown indicator signal that need to get under open state triggers and realizes, and therefore, is necessary to obtain shutdown indicator signal under open state.Wherein, shutdown indicator signal can be the waveform of shutdown pulse etc., and the present embodiment is not done concrete restriction to shutdown indicator signal.
About obtain the mode of shutdown indicator signal under open state, include but not limited to:
Under off-mode, whether detector switch button is selected;
If it is selected described switch key to be detected, generate shutdown indicator signal.
Wherein, the whether selected mode of detector switch button under open state, include but not limited to following mode: the implementation environment of the present embodiment is as shown in Figure 1 known, one end of switch key is ground connection, and under the state of ground connection, the electromotive force of switch key earth terminal is identical with the electromotive force of the earth, is 0 electromotive force, and the other end of switch key and the positive pole of power supply are connected, if switch key is selected, this end electromotive force is higher than 0, and now the electric potential difference at switch key two ends is higher than 0; If switch key is not selected, this end electromotive force is 0 electromotive force, and now the electric potential difference at switch key two ends is 0, therefore, and can be whether selected at detector switch button under open state by the electric potential difference at detector switch button two ends.
Further, after getting shutdown indicator signal, under the triggering of shutdown indicator signal, the AP of main equipment will generate shutdown command according to shutdown indicator signal.Wherein, the AP of main equipment generates the mode of shutdown command according to shutdown indicator signal, and the present embodiment is not done concrete restriction.During concrete enforcement, can in the corresponding relation of pre-stored shutdown indicator signal and shutdown command, search shutdown command corresponding to shutdown indicator signal, and the shutdown command using the shutdown command finding as generation.Particularly, the content of the shutdown command that the AP of main equipment generates according to shutdown indicator signal, can be one section of code, a symbol etc., and the content of the shutdown command that the present embodiment does not generate according to shutdown indicator signal the AP of main equipment is done concrete restriction.
In step 302, shutdown command is sent to protection IC, by protection IC, according to shutdown command, control MOSFET and disconnect.
Because battery exists overshoot or crosses in the process of using, put phenomenon: battery during in overshoot because temperature rises, interior pressure increases danger such as may causing on fire, blast; Battery is because electrolyte decomposition may cause battery behavior deteriorated when excessively putting, and therefore, the potential safety hazard of bringing for fear of over-charging of battery prevented putting the battery behavior causing deteriorated simultaneously, and battery conventionally can increase protection IC when design.During maximum current that the electric current that inside battery detected as protection IC allows higher than battery, by controlling MOSFET, disconnect battery is protected; During minimum current that the electric current that inside battery detected as protection IC allows lower than battery, by controlling MOSFET, disconnect battery is protected.Wherein, the maximum current that battery allows can be 10 milliamperes, 20 milliamperes, 26 milliamperes etc., and the maximum current that the present embodiment does not allow battery is not done concrete restriction.The minimum current that battery allows can be 1 milliampere, 2 milliamperes, 3 milliamperes etc., and the minimum current that the present embodiment does not allow battery is not done concrete restriction.
It should be noted that; protect in the present embodiment IC not only to there is foregoing circuit defencive function; and there is the function that receives shutdown command control MOSFET disconnection or receive start-up command control MOSFET UNICOM, in the present embodiment, be exactly that this function of utilizing existing protection IC can control MOSFET disconnection and connection realizes the control to battery and main equipment connection status.
Further, due to mobile terminal, a plurality of application programs may have been started in working order time, these application programs are not to close when closing simultaneously, but close successively in a certain order, be that the application program that mobile terminal is closed operation has certain time delay, if the application program in mobile terminal is power-off suddenly in the process of operation, not only can cause damage to the system of mobile terminal, and can produce harmful effect to the performance of mobile terminal, therefore, infringement mobile terminal being brought for fear of unexpected power-off, can be at the AP of main equipment before sending shutdown command to protection IC, to protection IC, send the delay switching-off instruction of the shutdown time delay of carrying system, thereby while guaranteeing mobile terminal power-off, application program is thoroughly closed.Particularly, the AP of main equipment, to the mode of the delay switching-off instruction of the shutdown time delay of protection IC transmission carrying system, includes but not limited to following mode:
First, determine the shutdown time delay of system;
Wherein, the shutdown time delay of system can be 8 seconds, 10 seconds, 15 seconds etc., and the present embodiment is not done concrete restriction to the shutdown time delay of system.About determining the mode of the shutdown time delay of system, the present embodiment is not done concrete restriction, while specifically implementing, can determine according to the performance of system.For example, when system is carried out under open state program is more, the load factor of the CPU of system is higher, and the stop of now system being opened will expend the longer time, therefore, and can the shutdown time delay setting of system is longer, as 15 seconds, 20 seconds etc.; When under open state, the program of system execution is less, the load factor of the CPU of system is lower, and the stop of now system being opened can not expend the longer time, therefore, can the shutdown time delay setting of system is shorter, as 5 seconds, 8 seconds etc.
Secondly, to protection IC, send the delay switching-off instruction of the shutdown time delay of carrying system, after the shutdown time delay of being carried in the time that receives shutdown command reaches delay switching-off instruction by protection IC, according to shutdown command, control MOSFET and disconnect.
About send the mode of delay switching-off instruction of the shutdown time delay of carrying system to protection IC, the present embodiment is not done concrete restriction, includes but not limited to the delay switching-off instruction of the shutdown time delay of carrying system to be sent to protection IC in the mode of notice, message.
Alternatively, in order to realize the ultrathin of mobile terminal, the manufacturer of mobile terminal is built in battery in the main equipment of mobile terminal conventionally, under the scene of main equipment that battery is built in to mobile terminal, though mobile terminal in off-mode, the battery in mobile terminal and main equipment still can discharge by internal circuit, therefore, in order to save electric energy, avoid battery and the electric discharge of the inner UNICOM of main equipment under off-mode, should make thoroughly to disconnect between battery and main equipment.In order to make thoroughly to disconnect between battery and main equipment, the AP of main equipment, after generating shutdown command according to shutdown indicator signal, can be sent to the shutdown command of generation protection IC, controls MOSFET disconnect by protection IC according to shutdown command.
Alternatively; because protection IC is before receiving shutdown command; received the delay switching-off instruction of the shutdown time delay of carrying system; therefore; after protection IC receives shutdown command; can't carry out immediately shutdown command; but whether the time of detecting reception shutdown command reaches the shutdown time delay of the system of carrying in delay switching-off instruction; if the time that receives shutdown command reaches the shutdown time delay of system; illustrate that now carrying out shutdown command can not bring infringement to mobile terminal; therefore, protection IC controls MOSFET disconnection according to shutdown command.
Whether the time that receives shutdown command about detecting reaches the mode of the shutdown time delay of the system of carrying in delay switching-off instruction, and the present embodiment is not done concrete restriction.During concrete enforcement, can be in the following way: first record protection IC receives the time of shutdown command, then take time of reception shutdown command of record is reference point, Real-time Obtaining current time, and then the shutdown time delay of the system of carrying in the time interval between the time of the reception shutdown command of the current time getting and record and delay switching-off instruction is compared, if the time interval between the time of the reception shutdown command of the current time getting and record is less than the shutdown time delay of the system of carrying in delay switching-off instruction, the time of judgement reception shutdown command does not reach the shutdown time delay of the system of carrying in delay switching-off instruction, if the time interval between the time of the reception shutdown command of the current time getting and record equals the shutdown time delay of the system of carrying in delay switching-off instruction, the time that judgement receives shutdown command reaches the shutdown time delay of the system of carrying in delay switching-off instruction.For example, it was 10 seconds that protection IC receives the shutdown time delay of carrying in shutdown time delay command, if protection IC receives the time of shutdown command, was 8 o'clock, and the 8 o'clock time that protection IC is received to shutdown command is reference point, Real-time Obtaining current time.If get current time, it is 8: 5 seconds, because current time is 10 seconds of shutdown time delay that are less than the system of carrying in delay switching-off instruction 5 seconds with the time interval that protection IC receives shutdown command, therefore, the time of judgement reception shutdown command does not reach the shutdown time delay of the system of carrying in delay switching-off instruction; If get current time, it is 8: 10 seconds; the time interval that receives shutdown command due to current time and protection IC is 10 seconds of shutdown time delay that equal the system of carrying in delay switching-off instruction 10 seconds; therefore, the time of judgement reception shutdown command reaches the shutdown time delay of the system of carrying in delay switching-off instruction.
In step 303, according to the off-state of MOSFET, control battery and main equipment disconnection.
After protection IC controls MOSFET disconnection according to shutdown command; MOSFET will be in off-state, and when MOSFET is during in off-state, inside battery does not have electric current to produce; internal circuit between battery and main equipment is in off state, and now battery and main equipment are disconnected completely.
So far, realized the disconnection of battery and main equipment by above-mentioned steps, after this process finishes, as user wishes that mobile terminal is again in running order, the method that the present embodiment provides also will be controlled battery and be connected with main equipment, specifically refer to following steps.
In step 304, under off-mode, obtain start indicator signal, and generate start-up command according to start indicator signal.
About obtain the mode of start indicator signal under off-mode, include but not limited to:
Whether selectedly under off-mode, detect starting key;
If it is selected starting key to be detected, generate start indicator signal.
Wherein, the whether selected mode of detector switch button under off-mode, include but not limited to following mode: the implementation environment of the present embodiment is as shown in Figure 1 known, one end of switch key is ground connection, and under the state of ground connection, the electromotive force of switch key earth terminal is identical with the electromotive force of the earth, is 0 electromotive force, and the other end of switch key and the positive pole of power supply are connected, if switch key is selected, this end electromotive force is higher than 0, and now the electric potential difference at switch key two ends is higher than 0; If switch key is not selected, this end electromotive force is also 0 electromotive force, and now the electric potential difference at switch key two ends is 0, therefore, and can be whether selected at detector switch button under off-mode by the electric potential difference at detector switch button two ends.
Alternatively, after getting start indicator signal, under the triggering of start indicator signal, the AP of main equipment will generate start-up command according to start indicator signal.Wherein, the AP of main equipment generates the mode of start-up command according to start indicator signal, and the present embodiment is not done concrete restriction.During concrete enforcement, can in the corresponding relation of pre-stored start indicator signal and start-up command, search shutdown command corresponding to start indicator signal, and the start-up command using the start-up command finding as generation.Particularly, the content of the start-up command that the AP of main equipment generates according to start indicator signal, can be one section of code, a symbol etc., and the content of the start-up command that the present embodiment does not generate according to start indicator signal the AP of main equipment is done concrete restriction.
In step 305, start-up command is sent to protection IC, by protection, IC controls MOSFET UNICOM according to start-up command.
In order to realize being connected of battery and main equipment, main equipment, after generating start-up command, need to be sent to the start-up command of generation protection IC, and IC is after receiving start-up command in protection, according to start-up command, controls MOSFET UNICOM.About main equipment, start-up command is sent to the mode of protection IC, the present embodiment is not done concrete restriction, includes but not limited to adopt the modes such as notice, message that start-up command is sent to protection IC.
In step 306, according to MOSFET UNICOM state, control being connected of battery and main equipment.
After protection IC controls MOSFET UNICOM according to start-up command; MOSFET will be in UNICOM's state, and when MOSFET is during in UNICOM's state, inside battery is by generation current; internal circuit between battery and main equipment is in open-circuit condition, and now battery and main equipment will be joined together.
The method that disclosure embodiment provides; by generate shutdown command according to the shutdown indicator signal getting under open state; and then shutdown command is sent to protection IC; by protection IC, controlled after MOSFET disconnection; whether according to the state of MOSFET, control battery is connected with main equipment; because MOSFET and protection IC are the existing parts on mobile terminal, thereby can realize and control battery and main equipment disconnection without extra installation switching device, reduce resource consumption.
