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.
