The BQ24800EVM evaluation module (EVM) is an SMBus 2-cell to 4-cell hybrid power boost mode battery charge controller with hybrid boost and processor hot monitoring. The input voltage range is between 4.5 V and 24 V, with a programmable output of 2–4 cells charge voltage and 128-mA to 8.128-A charge current. This EVM does not include the EV2400 interface device; this will have to be ordered separately to evaluate the BQ24800EVM.
- Host-controlled 2-S to 4-S battery buck charger with 3.2-V to 24-V input; 1-V to 19.2-V charging output
- Hybrid power boost mode to provide system power from adapter and battery simultaneously
- Peak power mode to optimize adapter utilization without discharging battery
- Battery-only boost mode to extend battery usable range
