General Description

FS8601HA 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.



With built-in N-MOSFET of low turn-on resistance.
Reduction in Board Size due to Miniature Package DFN-5.
