ML5206 - Cell Li-ion Rechargeable Battery Protection IC

General Description

The ML5206 is a protection IC with cell balancing funcion for the 3- to 5-cell Li-ion rechargeable battery pack.

It detects individual cell overvoltage and battery cell open-wire, and alerts by alarm output signal.

And cell balancing function is built in and it is automatically executed.
