FP8103
1A Linear Li-Ion Battery Charger in SOP8
General Description
The FP8103 is a standalone linear Li-ion battery charger with exposed pad SOP8 package. With
few external components, FP8103 is well suited for a wide range of portable applications. Charging
current can be programmed by an external resistor. In standby mode, supply current will be reduced to
around 55uA. Other features include UVLO, automatic recharge, charge status indicators and thermal
regulation.
