FS8820P-T

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.
