Applications
Lithium-Ion
/
FS326 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.
