CM1010-A 1S Li-Ion/LiPo Battery Protection IC (4.2V, OCP, SOT23-6)

Ensure absolute safety when building custom 1S power packs for micro drones, portable IoT devices, or repairing 18650 cells with the CM1010-A battery protection IC. Lithium batteries are highly volatile if abused, but this dedicated single-cell protection controller actively prevents catastrophic failures. It continuously monitors the cell's voltage and current, immediately disconnecting the load or charger in the event of an over-charge (exceeding standard 4.2V limits), over-discharge, or short circuit.

Designed to pair perfectly with standard dual N-channel MOSFETs (such as the ubiquitous 8205A), the CM1010-A allows you to build an ultra-compact Battery Management System (BMS) that fits directly onto the terminals of a small battery. Housed in a miniature SOT23-6 package and drawing virtually zero standby current, it offers industrial-grade safety for your DIY electronics without draining your battery during long storage periods.

Key Features:

• Comprehensive Safety: Protects 1S Li-Ion and LiPo cells against dangerous over-charge, over-discharge, and direct short-circuit events.

• Precise Over-Current Protection (OCP): Accurately monitors discharge rates, preventing thermal runaway and battery degradation in high-drain DIY projects.

• Ultra-Low Standby Current: Consumes microamps of power during normal operation, maximizing the shelf life of small-capacity batteries.

• Microscopic Footprint: The SOT23-6 package is the industry standard for tiny protection boards, easily fitting onto 18650 cell caps or flat LiPo pouches.
