The BQ24800 evaluation module (EVM) is an SMBus 1- to 4-cell hybrid power boost mode battery charge
controller with battery-only boost and processor hot monitoring. The input voltage range is between 4.5 V
and 24 V, with a programmable output of 1-4 cells charge voltage and 128-mA to 8.128-A charge current.
This EVM does not include the EV2400 interface device; it must be ordered separately to evaluate the
BQ24800 EVM.
