... General Description The FS312F-G battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to 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 ± ...

... At the same time, the CS pin is pull-up to VCC through an internal resistor. Note: When a battery is connected to FS312F-G for the first time, it may not enter the normal condition (dischargeable may not be enabled). In this case, short the CS and VSS pins or connect to a charger to restore to the normal condition ...
