The BMS026 evaluation module (EVM) is a complete charger module for evaluating the standalone single-
cell NVDC charger using any of the devices above.

This EVM features adjustable input current limit, charging current, and charging voltage. It also has the
abilty to test the D+/D- input source type detection, external input over-voltage protection, and simulate
battery high and low temperature conditions.
