Description
VIN (Pins 1, 20)
Input supply voltage, Connect a 1µF ceramic capacitor to power ground.ISET (Pin 8)
Charge-current programing and monitoring pin.Connect a resistor between this pin and the GND pin to set the charge current limit by Equation 2:
24000 I OUT = ---------------R ISET ( mA ) (EQ.2)
USBI (Pin 2)
USB power type selection logic input.When this pin is left floating or driven to logic LOW, the USB port is regarded as a low-power port with 100mA maximum output current.In such cases,
