• Manufacturer: Fortune Semiconductor Corporation

Rev. 1.0
1.
The FS312F-G battery protection IC is designed to
protect lithium-ion/polymer battery from damage or
degrading
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 FS312F-G
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.
