Overview

The BQ24725AEVM-710 evaluation module (EVM) is a complete charger module for evaluating a multicell synchronous notebook turbo boost charge using the bq24725A device. It is designed to deliver up to 4 A of charge current to Li-ion or Li-polymer applications. The charge current is programmable by SMBus interface through the EV2300 interface board The bq24725AEVM-710 does not include the EV2300 interface board. In order to evaluate the bq24725AEVM-710, a user must order the EV2300 interface board separately
