FP8102
1A Linear Li-Ion Battery Charger in SOP8/MSOP8
General Description
The FP8102 is a standalone linear Li-ion battery charger with exposed pad SOP8/MSOP8
package. With few external components, FP8102 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.
