1 / 12 page MITSUBISHI<Dig./Ana. INTERFACE> M62255FP GENERAL PURPOSE BATTERY CHARGER CONTROL IC ( / 12 ) New Product New Product TENTATIVE TENTATIVE BLOCK DIAGRAM PIN CONFIGURATION (TOP VIEW) 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 1 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 APPLICATION Note.P.C, Video camera and general battery charger for other digital equipment •ON/OFF control with low power dissipation mode.
