Justice, the connector of USB line define such as Fig. 6 b, can be seen that USB_Check and Power_EN has been shorted to GND in figure.
Current embodiment require that being used cooperatively with on/off circuit, referring to Fig. 7, wherein the working principle of on/off circuit exists
In:
1, VBAT is anode, thus the battery supply input terminal of circuit；
2, VBAT realizes the overcurrent and battery reverse connecting protection of system by F2 self-recovery fuse and Q2PMOS pipe；
3, the LC that FB4 and C55C56 forms input terminal is filtered, and realizes the noise filtering to input power；
4, U8 is DCDC lowering and stabilizing blood pressure power supply chip, by the configuration of L2, C57, R48, R49, is realized to cell voltage
Pressure-reduced and-regulated, then realized by C58, FB5, C59, C60 and the π type of out-put supply is filtered, reduce out-put supply noise；The of U8
One foot EN, for the enabled pin of the power supply chip, when EN is high, the power supply chip start-up operation output voltage, when EN is low
When, power supply chip does not work, and exporting is 0；
5, battery supply VBAT passes through overcurrent reverse connecting protection, and the filtered voltage of LC is VIN；R55 and this PMOS tube of Q1,
It is formed to the input control of VIN, when Power_EN floating, Q1 shutdown, without on voltage to R57, when Power_EN is grounded
When, Q1 is connected, and has voltage on R57, and internal resistance is minimum when due to PMOS conducting, and this application is also very by the circuit of Q1
Small, so the voltage being added on R57 is no better than VIN, and VIN and VBAT is also almost equal, so being added in the voltage on R57
No better than VBAT；
6, R57 and R59 forms resistor voltage divider circuit, and the maximum value of partial pressure should be less than the maximum value of MCU ADC input, point
The BAT_ADC of low noise is obtained by R45 and C67RC low-pass filtering after pressure, BAT_ADC is connected on the ADC pin of MCU, can
It is accurate to and its voltage is detected, the size of the voltage value has also just reacted the number of battery capacity, that is, realizes pair
The detection of battery capacity；
7, after R57 and R59 partial pressure, while using the pull down resistor R50 in this coupled capacitor of C7, with the EN foot of U8
Connection, when Power_EN is grounded in a flash, VIN is coupled after R57, R59 partial pressure by C7 voltage, and the EN foot of U8 is in short-term
Interior is high, so that U8 starts to work, 3.0VD has power supply output；There is output later by R2 and D11, the EN foot of U8 can be certainly
Locking is continuous electricity, so that U8 can continue working output；
8, Power_Protect is connect with the I/O port of MCU, after U8 has output, MCU to begin with electricity work, can also be incited somebody to action
The hard foot of Power_Protec is drawn high, so that U8 is continued working；
9, when shutdown is required, only need to be earth-free by Power_EN pin floating, then no voltage on R57, thus
BAT_ADC voltage be 0, MCU detect be 0 after be considered off-mode, thus start often shutdown before various protection acts,
Then Power_Protect pin is dragged down again, then no voltage on R50, does not export so that U8 does not work, to realize
Shutdown；
Summarize: Power_EN realizes the booting and shutdown of entire circuit, and C7 and D11 realize the direct control to U8EN foot
System, due to the one-way conduction of D11, the coupled voltages of C7 will not influence the level on R2R6 when booting, after booting, due to
The stopping direct current of C7 capacitor acts on, and the high level on D11 will not influence voltage on R45, would not also influence to battery capacity
Acquisition effect.
