ABLIC S-82Y1C Battery Protection ICs

ABLIC S-82Y1C Battery Protection ICs are designed for lithium-ion and polymer rechargeable batteries. The ABLIC S-82Y1C ICs feature high-accuracy voltage detection and delay circuits, making them ideal for protecting 1-cell battery packs from overcharge, over-discharge, and overcurrent conditions. An external overcurrent detection resistor allows the IC to deliver precise overcurrent protection with minimal temperature influence.

Features
