FP8207-18V 3A Multi-Cell Battery Switching Charger DataSheet

General Description
    The FP8207 is a 4.6V~18V input voltage, 3A multi cell synchronous step-down switching charger with few external components, FP8207 is well suited for a wide range of portable applications. Charging current can be programmed by an external current sensing resistor. With 600KHz switching frequency. The FP8207 employs a 2.4V float voltage feedback reference, so any desired battery float voltage up to 12.6V can be programmed with a resistor divider.Other features include UVLO, automatic recharge, charge status indicators and battery temperature monitor.
