FS312
Lithium-ion/Polymer Battery Protection IC
General Description
FS312 is a series of lithium-ion and lithium-polymer
rechargeable battery protection ICs with high accurate
voltage detection and delay circuits.
These ICs are suitable for protection of single cell
lithium-ion or lithium polymer battery packs from over
charge, over discharge and over current.
