The M66516 is a semiconductor laser-diode driver/controller.Its functions are the driving and laser power control of a specific type (Mitsubishi's R type laser) of semiconductor laser diode, in which the cathode of a semiconductor laser diode is connected in stem structure to the anode of a monitoring photodiode.
The IC has a laser drive current output pin of source type and is capable of driving a laser diode on a maximum bias current of 30mA and a maximum switching current of 120 mA, which is switched at a rate of 20Mbits/sec.
Since the M66516 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.
