ACEDW01

One Cell Lithium-ion/Polymer Battery Protection IC

Description

This protection IC was developed for use with lithium-ion/lithium polymer 1-cell serial batteries.

It detects overcharge, overdischarge, discharge overcurrent and other abnormalities, and functions to

protect the battery by turning off the external MOSFET.

The IC also has a built-in timer circuit (for detection delay times), so fewer external parts can be used in

protection circuit configuration.
