FUNCTION
Not Connected . Pin not connected internally, float or connect to VSS.
Device Ground. Connect directly to the negative terminal of the battery
cell. Connect the sense resistor between VSS and SNS.
Voltage Sense Input. The voltage of the battery cell is monitored through
this input pin.
Power-Supply Input. Connect to the positive terminal of the battery cell
through a decoupling network.
Serial Data Input/Output. 2-Wire data line. Open-drain output driver.
