FP8203
2A Switch-Mode Li-Ion Battery Charger
General Description
The FP8203 is a highly integrated switch-mode Li-Ion Battery Charger. With few external
components, FP8203 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, FP8203 can
use of small external components. Other features include UVLO, automatic recharge, charge status
indicators and battery temperature monitor.
