M66515FP
DESCRIPTION
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 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 30m A and a maximum switching current of 120m A, 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. ∗: Automatic Power Control FEATURES
- Built-in sample-hold circuit for internal APC function
- High speed switching (40Mbps)
- Large drive current (150m A max.)
- Capable of setting bias current (30m A max.)
- 5V single power supply APPLICATION Semiconductor laser-diode applied equipment
