MITSUBISHI MITSUBISHI 〈DIGITAL 〈DIGITAL ASSP ASSP 〉 〉 M66510P/FP M66510P/FP LASER-DIODE DRIVER LASER-DIODE DRIVER DESCRIPTION The M66510 is a semiconductor laser diode driver that drives a semiconductor laser of the type whose cathode and the anode of monitor photodiode are connected to the stem. Laser driving current of up to 120m A can be set by applying constant voltage from outside to drive the laser diode. It operates from a 5V single power supply, allowing switching of laser driving current at a speed of 20M bits/sec. - : Our semiconductor laser is of R type. Features - Built-in two outputs for monitoring laser power (parator output and analog output) - With laser driving current forced off pin - High-speed switching (20M bits/s) - High driving current (120m A max.) - 5V single power supply APPLICATION Laser beam printer PIN CONFIGURATION (TOP VIEW) VCC1 CURRENT SETTING INPUT 1 CURRENT SETTING LOAD OUTPUT 1 CURRENT SETTING INPUT 2 CURRENT SETTING LOAD OUTPUT 2 LASER CURRENT FORCED OFF INPUT CURRENT SETTING LOAD OUTPUT 3 MONITOR LOAD INPUT 1 MONITOR LOAD INPUT 2 20 → 1RO 19 → 2RO 18 → LD VL1 → 2 1RC ← 3 VL2 → 4 2RC ← 5 VOFF → 6 3RC ← 7 GND1 8 LASER CURRENT LOAD OUTPUT 1 LASER CURRENT LOAD OUTPUT 2 LASER DIODE OUTPUT MONITOR DIODE INPUT DATA INPUT MONITOR PARATOR OUTPUT MONITOR ANALOG OUTPUT DUTY CONTROL INPUT M66510P/FP GND2 16 ← PD 15 ← DATA 14 VCC2 13 → CO 12 → MO 11 ← CD 1RM → 9 2RM → 10 Outline 20P4K BLOCK DIAGRAM MONITOR OUTPUT MO 12 PARATOR OUTPUT CO 13 1RO 20 2RO 19 LINEAR AMPLIFIER PARATOR (Vref = 1.2V) CURRENT SETTING VL1 2 INPUT 1 1RC 3 CURRENT SETTING VL2 4 INPUT 2 2RC 5 CONSTANT CURRENT SOURCE (IL1) Max. 60m A CONSTANT CURRENT SOURCE (IL2) Max. 30m...
