M-TYPE CW LASER DIODE DRIVER
FEATURES
BLOCK DIAGRAM
Optimised for M-type laser diodes
(single supply, case grounded)
CW operation up to 350 mA from a single supply of 3.6 to 15 V
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.e. if the laser diode is damaged or the feedback
current path fails)
Two feedback inputs permit all current laser diode types to be
used (M/P/N configurations)
Modulation via the feedback inputs possible
Wide monitor current range from 2.5 µA to 6.25 mA

... 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 ...
