Product Overview
The AT1002-Y is a high-precision protection integrated circuit for single-cell lithium-ion / lithium-polymer rechargeable batteries. It integrates overcharge, overdischarge, discharge overcurrent, charging overcurrent, and short-circuit protection with high-precision voltage detection.
The AT1002-Y is one of five factory-programmed variants of the AT1002 family, each with a different overcharge / overdischarge threshold combination. This variant is configured with VOC=3.650V, VOD=2.550V, and Sleep Mode: Yes. It features 0V charging function, load and charger detection, and low 2.2µA typical operating current.
