General Description

The FS8820P battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell lithium-ion/polymer battery powered systems, such as cellular phones.
The ultra-small package and less required external components make it ideal to integrate the FS8820P into the limited space of battery pack. The accurate 50mV overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage.



With built-in N-MOSFET of low turn-on resistance.
Reduction in Board Size due to Miniature Package TSSOP-8.
