Auxiliary Voltage Input Number 0
Serial Clock Input. Input only 2-wire clock line. Connect this pin to the clock signal of the 2-wire
interface. This pin has a 0.2μA typical pulldown to sense disconnection.
Serial Data Input/Output. Open-drain 2-wire data line. Connect this pin to the clock signal of the 2-
wire interface. This pin has a 0.2μA typical pulldown to sense disconnection.
Current-Sense Input. Connect to the handset side of the sense resistor.
Device Ground. Connect to the battery side of the sense resistor.
EEPROM Programming Voltage Input. Connect to external supply for production programming.
Connect to V
Voltage Out. Supply for auxiliary input voltage measurement dividers. Connect to high side of
resistor-divider circuits.
Battery Voltage Input. The voltage of the cell pack is measured through this pin.
Power-Supply Input. 2.5V to 4.5V Input Range. Connect to system power through a decoupling
network.
