Description
Current sensing using an external sensing resistor RSNS
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
General purpose bi-directional I/O pin 2
Ground
Oscillator input. Connect to an external resistor R=200kΩ, the oscillator
frequency is around 4.5MHz
No connection.
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
