ML5233 - Cell Li-ion Rechargeable Battery Protection IC

Datasheet Summary

Description

The ML5233 is a protection IC for the 4- to 10-cell Li-ion rechargeable battery pack.

It detects individual cell overvoltage/undervoltage and the pack overcurrent/over-temperature, and then automatically turns on or turns off the external charge/discharge NMOS-FETs accordingly.

Features

ML5233 4- to 10-Series Cell Li-ion Rechargeable Battery Protection IC FEDL5233-05 January 9, 2024 ■ General Description The ML5233 is a protection IC for the 4- to 10-cell Li-ion rechargeable battery pack. It detects individual cell overvoltage/undervoltage and the pack overcurrent/over-temperature, and then automatically turns on or turns off the external charge/discharge NMOS-FETs accordingly. Also the ML5233 can be cascaded to handle battery packs with more than 10 cells. ■ Features • 4 to 10 cell high-precision overvoltage and undervoltage detection function Voltage monitoring function for individual cells Overvoltage detection threshold 4.25 V, Detection accuracy: ±15 mV (max) Undervoltage detection threshold 2.
