M62254FP

Mitsubishi Semiconductor < DIGIANA Interface > M62254FP Standard Battery Charger Controller DESCRIPTION The M62254FP is designed as standard battery charger controller. The M62254FP has functions which require for the battery charge control on single chip. Not only the combination of M62254 and MCU capable of handling battery charge control, but also it is capable of monitoring battery temperature, prevent from over current or voltage, using minimal peripherals. It also has feedback function to the primary source of SW power supply, which can used to control feedback of charge current and output voltage.
