The bq24725A/735 evaluation module (EVM) is a complete charger module for evaluating a multicell synchronous notebook turbo boost charge using the bq24725A/735 devices. It is designed to deliver up to 4 Aof charge current to Li-ion or Li-polymer applications. The charge current is programmable by SMBus interface through the EV2300 interface board. The bq24725A/735EVM does not include the EV2300 interface board. In order to evaluate the bq24725A/735EVM, a user must order the EV2300 interface board separately. The bq24725A/735 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multichemistry battery charging applications. The bq24735 supports the Turbo Boost mode by allowing the battery to discharge energy to the system when system power demand is temporarily higher than adapter maximum power level so that the adapter does not crash. The bq24725A/735 uses two charge pumps to separately drive n-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection. SMBus-controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be easily programmed by the system power management microcontroller.
