ACE4722 Description
The ACE4722(Note 1) is a PWM switch-mode battery charger controller that can be powered by photovoltaic cell with maximum power point tracking function. The ACE4722 is specially designed for charging 1 or multi-cell lithium ion batteries or LiFePO4 batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage is set by the external resistor divider.
