Description
Technical field
It the utility model is related to cell phone apparatus field, more particularly to a kind of mobile phone terminal with internal battery.
Background technology
With the continuous development of mobile phone, current a big chunk mobile phone is all to use internal battery.Using interior in mobile phone
Putting battery has several big advantages：Mobile phone can design more attractive in appearance, frivolous；User cannot arbitrarily change battery, so can be with
Avoid user because use do not match or underproof battery caused by some potential safety hazards；Same size, in-built electrical
The capacity for the removable battery of ratio that the capacity in pond can be done is bigger.Due to these advantages so that many manufacturers are in design mobile phone
When tend to the scheme using internal battery.
But using internal battery but also there are some shortcomings in mobile phone terminal：
For user, because internal battery can not be extracted in mobile phone terminal, when extremely, i.e., cell phone system is hung
When the cpu system of mobile phone crashes, even if by the reset key of mobile phone terminal, that is, when restart mobile phone and be also not responding to, due to
Power supply non-cutting between internal battery and cpu system, can only tear mobile phone open in a manner of internal battery to be pulled come
Cpu system power-off is given, to wish to make mobile phone to recover normal, and the problem of due to internal battery structure design, mobile phone is taken apart
It is more complicated for a user, general user is not it is difficult to ensure that damaging the situation of cell phone appearance either internal components
It is lower to remove internal battery from mobile phone terminal；
Secondly, the complete machine of many mobile phone terminals is after dispatching from the factory, and due to that may export abroad, centre will be after very long
Transport, customs inspection custom clearance and sales field place etc. time, some mobile phone terminals may be placed one or two months after dispatching from the factory.
If mobile phone terminal when dispatching from the factory, the internal battery electricity ratio in mobile phone terminal is relatively low or the capacity of internal battery in itself
It is just not high, because mobile phone is from power consumption, after user takes these mobile phone terminals, original electricity of the internal battery of mobile phone terminal
Amount depleted may cannot be started up to self-protection state, the mobile phone terminal of this when, even if plugging charging
Device charges to internal battery, it is also possible to may require that the time for expending more than ten minutes or even longer time to make the electricity of internal battery
Pressure returns to start voltage.But because the charging interval under this state is longer, for many users, in mobile phone terminal
After inserting charger charging a period of time, if mobile phone terminal does not react also, user just will be considered that mobile phone terminal breaks down, no
Can start shooting to charge, and this mobile phone terminal with internal battery is experienced poor for a user.

In Fig. 1, Voltage Reference represent reference voltage, and Oscillator represents crystal oscillator,
Digital Logic＆Counter represent Digital Logic control and counter, and GND represents ground connection, Output Discharge tables
Show output electric discharge, Turn-On Slew Rate Controlled Driver represent that metal-oxide-semiconductor starts control driver.
Referring to shown in Fig. 1 and Fig. 2, in load switch chip Load switch circuit, when load switch closes pin
When OFF is low level, the metal-oxide-semiconductor conducting in load switch chip；Pin OFF, which is closed, when load switch is changed into high from low level
During level, the metal-oxide-semiconductor in load switch chip is closed.Therefore, in the case where mobile phone terminal is in open state, CPU systems can be passed through
The input/output terminal GPIO of system sets the state that load switch closes pin OFF, that is, to set load switch to close pin OFF is low electricity
Flat or high level, accordingly to turn on metal-oxide-semiconductor or close metal-oxide-semiconductor, so as to when metal-oxide-semiconductor is closed, make mobile phone terminal
Internal battery and mobile phone cpu system between power supply cut-out；
When metal-oxide-semiconductor is off state, load switch resets input pin nSR0 and is changed into low level from high level, you can will
Metal-oxide-semiconductor is changed into conducting state, therefore load switch reset input pin nSR0 is pulled upward into internal battery by first resistor R1
On Battery positive pole so that it is high level state that load switch, which resets input pin nSR0, while is connected to the key of mobile phone
On；When mobile phone power-on key is pressed so that load switch resets input pin nSR0 and is changed into low level from high level, you can touches
Send out load switch chip and open metal-oxide-semiconductor so that internal battery connects with cpu system power supply.
When metal-oxide-semiconductor is off state, the level that load switch is waken up on pin SYS_WAKE is changed into high electricity from low level
It is flat, metal-oxide-semiconductor can be also changed into conducting state, therefore load switch is waken up into pin SYS_WAKE and passes through the electricity of second resistance R2 and the 3rd
Resistance R3 partial pressures are connected on the voltage output end VCHG of charger；When charger is inserted, load switch wakes up pin SYS_
WAKE is changed into high level from low level, you can triggering load switch chip opens metal-oxide-semiconductor so that internal battery supplies with cpu system
Electric connection gets up, while is charged by the charging circuit part of cpu system to internal battery.
When metal-oxide-semiconductor is in opening, load switch resets input pin nSR0 and is changed into low level from high level, you can will
Metal-oxide-semiconductor is closed a period of time and is then turned on, thus by load switch reset input pin nSR0 be pulled upward to by first resistor R1 it is built-in
On battery Battery positive pole so that it is high level state that load switch, which resets input pin nSR0, while is connected to opening for mobile phone
On switch；When mobile phone power-on key is pressed so that load switch resets input pin nSR0 and is changed into low level from high level, i.e.,
It can trigger load switch chip to be then turned on metal-oxide-semiconductor closing a period of time so that internal battery disconnects one section with cpu system power supply
Time, so as to make cpu system carry out power-off restoration.
Shown in Figure 2, mobile phone terminal is when dispatching from the factory, and after system test is all finished, manufacturing firm can lead to
The Transportation Model that software interface opens mobile phone terminal is crossed, is closed by the input/output terminal GPIO of cpu system to set load switch
It is high level to close pin OFF, the metal-oxide-semiconductor closed in load switch chip, so as to by the internal battery of mobile phone terminal and cpu system it
Between power supply cut-out, then mobile phone terminal is attached in packing box again, so it is prevented that built in the in-fighting of mobile phone causes
Battery, which is crossed, to be put；
When mobile phone terminal is taken out in packing box, it can be activated by long-press key or insertion charger
Load switch chip opens metal-oxide-semiconductor, the power supply in mobile phone terminal between internal battery and cpu system is connected, so
Can normally uses mobile phone terminal；Now, crossed and put without the in-fighting because of mobile phone due to internal battery, therefore without special
Mean that internal battery charging can realize the normal boot-strap of mobile phone terminal, avoid user and wait as long for mobile phone terminal charging
And the time-consuming problem brought；
When mobile phone crashes or cpu system is in extension death situation state, long-press key can be passed through so that load switch core
The metal-oxide-semiconductor of piece is then turned on after closing a period of time, thus can be in order to avoid user plugs the internal battery of mobile phone and directly reached
Purpose to cpu system power-off so that cpu system resets again returns to normal condition.
Although preferred embodiment of the present utility model described in detail above, it is to be clearly understood that for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
