NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
Pin Descriptions
PIN
NUMBER PIN NAME
BRIEF DESCRIPTION
1
VCELL1 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.
2
CB1 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.
3
VCELL2 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.
