M62240 Overview
The M62240FP is a general purpose battery charger control IC. It can control all of the sequence needed for battery charging, it also has functions such as detection of battery temperature, a protection against over-current/voltage, a safety timer and so on. Moreover, it can adapt to charge Ni-Cd, Ni-MH batteries by adding few peripheral ponents.
M62240 Key Features
