HY2120

2 lithium-ion/lithium polymer battery protection ICs

1. Overview

HY2120 series ICs, featuring built-in high-precision voltage detection circuit and timing circuit, are designed for 2 in-series rechargeable lithium-ion/lithium polymer batteries

Battery Protection IC.

This series of ICs is suitable for protecting 2-series in-series rechargeable lithium-ion/lithium-polymer batteries against overcharging, overdischarging, and overcurrent conditions.

Available as a substitute for Ricoh's LITHIUM LIGHTR5460NSeries.Same performance, half the price!
