Serial Data Input/Output. Open-drain 2-wire data line. Connect this pin to the DATA signal of the 2-
wire interface. This pin has a 0.2µA typical pulldown to sense disconnection.
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.
Connect to Ground. Connect to VSS during normal operation.
Quick-Start Input. Allows reset of the device through hardware. Connect to GND if not used.
No connect. Do not connect.
Battery Voltage Input. The voltage of the cell pack is measured through this pin.
Alert Output. Active-low interrupt signaling low state of charge. Connect to interrupt input of the
system microprocessor.
Power-Supply Input. 2.5V to 4.5V input range. Connect to system power through a decoupling
network. Connect a 10nF typical decoupling capacitor close to pin.
Ground. Connect to the negative power rail of the system.
Exposed Pad (TDFN only). Connect to ground.
