DESCRIPTION
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
.
24P2Q-A
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. (Power save)
