FUNCTION
Serial Clock Input. 2-Wire clock line. Input only. Connect this pin to the CLOCK
terminal of the battery pack. Pin has an internal pulldown (I PD ) for sensing
disconnection.
Serial Data Input/Output. 2-Wire data line. Open-drain output driver. Connect this pin
to the DATA terminal of the battery pack. Pin has an internal pulldown (I PD ) for sensing
disconnection.
General Purpose Input/Output. Open-drain output driver with input sense. Connect
to a pull up resistor for bidirectional operation.
Sense Resistor Connection. Connect to the negative terminal of the battery pack.
Connect the sense resistor between V SS and SNS.
Device Ground. Connect to the negative terminal of the Li+ cell outside the cell
protection FETs. Connect the sense resistor between V SS and SNS.
Connect to Ground. Connect to the negative terminal of the Li+ cell outside the cell
protection FETs.
Voltage Sense Input. The voltage of the Li+ cell is monitored through this input pin.
Power-Supply Input. Connect to the positive terminal of the Li+ cell through a
decoupling network.
