... CW operation up to 350 mA from a single supply of 3 Rapid soft start after power-on Simple power adjustment via an external resistor Integrated reverse polarity protection for the iC and laser diode Strong suppression of transients with small external capacitors; integrated flyback path Permanent shutdown with excessive temperature and overcurrent (i ...

... In the event of failure, such as overcurrent in the laser path with a lack of feedback, for example, a quick power lockout is activated. The shutdown persists until power is reapplied, permitting a restart. The strain on power packs and batteries is relieved and the laser class is retained even in the event of a dis- turbance ...

... If the monitor diode or the bias 150us 200us 250us resistor RM fail, the device is shut down in less than 600 µs, provided that the supply voltage applied is high enough. When modulating the laser current via pin MDK, ex- cessive voltage occurring at pin MDA also may cause a shutdown ...
