Multicell Synchronous Switchmode Reference Design

This reference design is a complete charger module for evaluating a multicell (1 to 4 cells) synchronous notebook charger using the bq24707 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 an SMBus interface through the EV2300 interface board. The reference design does not come with the EV2300 interface board: so it must be ordered separately. The design contains high-efficiency: synchronous battery chargers: offering low component count for space-constrained: multi-chemistry battery-charging applications. The charge voltage: charge current: input current: and flexible charge option are programmable via SMBus interface.
