The bq25700A evaluation module (EVM) is an SMBus controlled NVDC (narrow voltage DC) buck boost charge controller with N-CH MOSFET Selector and Current Monitoring. The input voltage range, for the buck converter, is between 3.5V and 24 V, with a programmable output of 1–4 cells and a charge output current range of 128mA to 8.128 A. This EVM doesn’t include the EV2400 interface device; this will have to be ordered separately to evaluate the bq25700A EVM.
