Current sensing using an external sensing resistor R
Supply voltage
Active low reset or as active high OTP program write
Test mode input. Test=1 is the normal mode. Test Mode is
initiated while Test=0 before reset. This pin is suggested
pulled inactive high for regular operation without Test
Mode.
General purpose bi-directional I/O pin 0
General purpose bi-directional I/O pin 1
Ground
General purpose bi-directional I/O pin 2
Oscillator input. Connect to an external resistor R=200kΩ,
the oscillator frequency is around 4.5MHz
PWM capacitor input for selection of the RC time constant
in generating voltage reference.
Source or sink LED0 display
Source or sink LED1 display
Battery temperature sensing input
Battery ID-type selected by the voltage drop across the
series resistor. Battery ID is for identification of either
thick, thin battery or other selected types
Battery input voltage
Charge control output to drive pass transistor
