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
