M62240FP
Single Chip Battery Charger Control IC
Description
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 components.
The IC has the feedback control of the charge current and output voltage.
Features
• Low voltage (3 V) operation
• Built-in following functions and circuits;
Application
Battery charger for video cameras and handheld telephones, etc.
