Battery cell 1 voltage input. This pin is used to monitor the voltage of this battery cell internally.
The voltage of an individual cell can also be monitored externally at pin AO.
The X3100 monitors 4 battery cells. The X3101 monitors 3 battery cells.
Cell balancing FET control output 1. This output is used to switch an external FET in order to
perform cell voltage balancing control. This function can be used to adjust an individual cell voltage
(e.g. during cell charging). CB1 can be driven high (Vcc) or low (Vss) to switch the external FET
ON/OFF.
Battery cell 2 voltage. This pin is used to monitor the voltage of this battery cell internally. The voltage of an individual cell
can also be monitored externally at pin AO.
The X3100 monitors 4 battery cells. The X3101 monitors 3 battery cells.
