BQ24725EVM-542

Evaluation Board, Power Management, Battery Charger

The bq24725EVM evaluation module also referred to as HPA-542 is a complete charger module for evaluating a multicell synchronous notebook charge using the bq24725 devices. It is designed to deliver up to 4A of charge current to lithium ion or lithium polymer applications. The bq24725 is a high efficiency, synchronous battery charger, offering low component count for space constraint, multi chemistry battery charging applications. The bq24725 has a highly integrated battery charge controller designed to work with external host commands. The bq24725 uses two charge pumps to separately drive n-channel MOSFETs ACFET, RBFET and BATFET for automatic system power source selection. The charge voltage, charge current, input current, and flexible charge option are programmable with a SMBus interface. The bq24725 does not include the EV2300 interface board. To evaluate the bq24725, the EV2300 interface board must be ordered separately.
