* Information section). The DRV pin is internally clamped to 6.5V below VCC. VCC (Pin 7): Input Supply Voltage. VCC ranges from 8.8V to 12V when charging. If VCC drops below VBAT + 54mV, for example when the input supply is disconnected, then the IC enters sleep mode with ICC < 30µA. Bypass this pin w
