LASER-DIODE DRIVER
As the IC is equipped with a pin to provide a forced OFF of
current circuit, it is possible to prevent a large current flowing
through laser diodes at the moment of power ON.
Regarding the detection of laser power, a monitor current
generated by a monitoring photodiode, which is incorporated
in laser unit, is drawn and converted into changes in voltage
by means of an external resistor, in order to output as an ana-
log signal. Simultaneously, the converted voltage is com-
pared with the internal reference voltage, thence the result is
output in TTL level as logic information.
FUNCTION
The M66512 is a semiconductor laser-diode driver for driving
a specific type (Mitsubishi’s N type) of laser, in which the an-
ode 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 con-
stant voltage from an external source. For that purpose, the
M66512 has two voltage applying pins, which they are inde-
pendent each other, This mechanism makes it possible to set
a drive current with great accuracy.
