M66512FP

MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66512P/FP M66512P/FP LASER-DIODE DRIVER LASER-DIODE DRIVER DESCRIPTION The M66512 is a semiconductor laser-diode driver for driving a specific type* of semiconductor laser, in which the anode of a semiconductor laser diode is connected in stem structure to the cathode of a monitoring photodiode. The amplitude of laser drive current is set by applying a voltage from an external source. the M66512 is capable of driving laser diodes on a maximum current of 120 mA. It operates on a 5-V single power supply and switches laser drive current at a rate of 40 Mbit/s. *: The N type of Mitsubishi’s semiconductor lasers. FEATURES Two kinds of outputs for monitoring laser power built in. (comparator output and analog output) Pin provided for forced OFF of current circuit. High speed switching (40 Mbit/s) Large drive current (120mA max.) 5V single power supply APPLICATION Laser beam printers PIN CONFIGURATION (TOP VIEW) VCC1 CURRENT SETTING INPUT 1 VL1 CURRENT SETTING LOAD OUTPUT 1 1RC CURRENT SETTING INPUT 2 VL2 CURRENT SETTING LOAD OUTPUT 2 2RC LASER CURRENT FORCED OFF INPUT VOFF CURRENT SETTING LOAD OUTPUT 3RC GND1 MONITORING LOAD INPUT 1 1RM MONITORING LOAD INPUT 2 2RM 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 RO LOAD OUTPUT NC LD LASER DIODE OUTPUT GND2 PD MONITORING DIODE INPUT DATA DATA INPUT VCC2 MONITORING CO COMPARATOR OUTPUT ANALOG MO MONITORING OUTPUT NC LASER CURRENT Outline 20P4 20P2N-A NC: No C...
