DESCRIPTION

SC8821 is a Li+ battery protection circuit with built-in MOSFET. It is

suitable for protecting LI+ battery against damage from over

charge, over discharge, and over current. It contains high accurate

voltage detection and delay circuits.

FEATURES

* Built-in low equivalent on-resistance (30m

Ω) N-type MOSFET

* Low supply current

* Overcharge detection 4.28V, overcharge release 4.10V

* Overdischarge detection 2.50V, overchdisarge release 2.90V

* Over current detection 0.15V and short current detection 1.00V

* Built-in detection time delay of overcharge, overdischarge and

overcurrent

* Charger detection

* Reset resistance for over current protection

* Wide supply voltage range

APPLICATIONS

* Protection IC for One-Cell Li+ Battery
