CM112F-DAC: DFN1.0*1.0-4L Package with 4.475V Overcharge Protection Voltage and Shipping Mode for Single Cell Battery Protection IC

CM112F-DAC

Shipping Mode Integrated Single Cell Battery Protection IC

Overview

The CM112F-DAC features a high-precision voltage detection circuit and delay circuit, which detects the battery’s voltage and current to provide protection against overcharging, over-discharging, and over-current. It is suitable for protection circuits of single lithium-ion/lithium polymer rechargeable batteries and includes a shipping mode to meet the needs of maritime transport and long-term storage for small capacity battery packs.
