ACE4722 5A, Multi-Chemistry Battery Charger IC With Photovoltaic Cell MPPT Function 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. The constant charging current is programmable with a single current sense resistor. Deeply discharged batteries are automatically trickle charged at 15% of the programmed constant charging current until the cell voltage exceeds 66.7% of the regulation voltage.
