Some parametric limits are subject to change.
PIN CONFIGURATION (TOP VIEW) The M62255FP is intended to be used a general purpose battery charger control for Note PC.
The M62255FP contains the functions which are required for the battery charge control ,on single chip using low peripheral component requirement .
The M62255FP can handle battery charge control, monitor battery temperature and prevent from over current and voltage with microcomputer.
It contains DC-DC converter circuit which can be used for the feedback control of the charge current and the output voltage.
It is the best fit for Smart Battery Charger.
FEATURES •Built-in 3 wire serial data interface for MCU.
•Built-in multiplexer and level magnification circuit with 4 input ports.
•Built-in DC-DC converter circuit for PWM function •Built-in two current detection circuits.
These circuits can detect charge current and discharge current •ON/OFF control with low power dissipation mode.
