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/Out. 2-Wire data line. Open-drain output driver. Connect this pin
to the DATA terminal of the battery pack. Pin has an internal pull-down (I
sensing disconnection.
Serial Clock Input. 2-Wire clock line. Input only. Connect this pin to the CLOCK
terminal of the battery pack. Pin has an internal pull-down (I
disconnection.
No Connection. (Only present on TDFN package).
Sense Resistor Connection. Connect to the negative terminal of the battery
pack. Connect the sense resistor between VSS and SNS.
Programmable I/O Pin. Can be configured as input or output to monitor or control
user-defined external circuitry. Output driver is open drain. This pin has a weak
internal pulldown (I
