The M66515 is a semiconductor laser-diode driver/controller.Its functions are the driving and laser power control of a specific type (Mitsubishi's N type laser) of semiconductor laser diode, in which the anode of a semiconductor laser diode is connected in stem structure to the cathode of a monitoring photodiode.
The M66515 IC has a laser drive current output pin of sink type and is capable of driving a laser diode on a maximum bias current of 30mA and a maximum switching current of 120mA, which is switched at a rate of 40Mbit/s.
Since the M66515 has a built in sample-hold circuit, it is possible to realize an internal APC+ system that requires no external device for laser power control.
