No liability is assumed as a result of the use of this product. No rights under any patent accompany the sales of the product. Website: Rev. 1/21 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. Features Standalone Linear Charger for Single Cell Li-Ion Batteries No External MOSFET, Sense Resistor, or Blocking Diode Required Up to 1A Programmable Charge Current Preset Charge Voltage with 1% Accuracy Automatic Recharge Trickle Charge Voltage C/10 Charge Termination 55uA Standby Supply Current Charge Status Indicators for No Battery and Charge Failure Display Soft-Start to Limit Inrush Current Thermal Protection Applications Portable Information Appliances Charging Docks & Cradles Cellular Phones & PDAs Handheld Computers Typical Application Circuit CHRGSTDBY FP8102 This datasheet contains new product information.
