S-8209ABD-T8T1U

The S-8209A Series from ABLIC Inc., including the S-8209ABD-T8T1U, is a versatile battery protection IC for lithium-ion and lithium polymer rechargeable battery packs. It integrates a high-accuracy voltage detection circuit and a delay circuit, enabling robust protection against overcharge, overdischarge, and facilitating cell-balance functions for multi-cell configurations.

Key electrical specifications include an overcharge detection voltage range of 3.55 V to 4.40 V with ±25 mV accuracy, and an overdischarge detection voltage range of 2.0 V to 3.0 V with ±50 mV accuracy. The device also features cell-balance detection and release voltages within similar ranges. It operates efficiently with a low current consumption of 7.0 μA maximum.

Designed for flexibility, the S-8209ABD-T8T1U allows for settable delay times via an external capacitor and provides control over charging, discharging, and cell-balance functions through CTLC and CTLD pins. It supports two types of cell-balance functions: charge and discharge. The IC is housed in an 8-pin TSSOP package, suitable for surface mount applications, and operates across a wide temperature range of -40°C to +85°C.
