ML5236 Overview
The ML5236 is an analog front-end IC intended for 14-cell Li-ion rechargeable battery protection systems. With integrated individual cell voltage monitor and charge/discharge current monitor functions, it protects cell overvoltage, cell undervoltage, and pack over-current working with an external microcontroller (MCU). Also, it is equipped with the short-circuit protection function, which autonomously turns off the...
