Description
- TIDA-00038, This reference design is a complete charger module for evaluating a multi-cell (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
