rod P w Ne DESCRIPTION uct A NT MITSUBISHI<Dig./Ana. INTERFACE> GENERAL PURPOSE BATTERY CHARGER CONTROL IC Notice: This is not a final specification. 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 ponent requirement . The M62255FP can handle battery charge control, monitor battery temperature and prevent from over current and voltage with microputer. 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.
