APPLICATIONS

Lithium-Ion Rechargeable Battery

DESCRIPTION:

The AT1002 series is equipped with high-precision voltage detection circuits and delay circuits, which enable protection against overcharging, overdischarging, and overcurrent by detecting the battery's voltage and current. It is suitable for the protection circuit of single-cell lithium ion/lithium polymer rechargeable batteries.
