The ISL94203EVAL1Z evaluation kit facilitates testing of the ISL94203 Li-ion battery pack monitor and control ICs. The ISL94203 monitors cell voltage, current and temperature. It converts the cell voltages, pack current and temperatures to 12-bit digital values, provides cell balance control, and provides complete stand-alone battery pack operation.

The ISL94203 default stand-alone operation can be overridden by an external microcontroller. The PC graphical user interface (GUI) supports the hooks needed to monitor stand alone operation and to demonstrate operation with an external microcontroller.
