LASER-DIODE DRIVER
FUNCTION
The 66510 is a semiconductor laser diode driver that drives a
semiconductor laser of the type (our R type) whose cathode
and the anode of monitor photodiode are connected to the
stem. Using the R type laser allows direct fixing the laser on
a device for easy installation, thus improving its radiation effi-
ciency.
Laser driving current is set by applying voltage from outside.
The M66510 is equipped with two independent voltage ap-
plying pins to provide higher accuracy of setting the current
value.
It is also equipped with a laser current forced off pin to pre-
vent overcurrent from flowing into the laser diode at the
power-ON time.
For detection of laser power, the monitor current of monitor
photodiode built in the laser is converted into voltage by an
external resistor to generate an analog output, and simulta-
neously the result of comparison with the internal reference
voltage is output as TTL-level logic information.
