2.4 V CW LASER DIODE DRIVER  
Rev D1, Page 1/8  
FEATURES  
APPLICATIONS  
Battery-powered LD modules  
LD Pointers  
Laser levels  
CW operation up to 90 mA from 2.4 to 6 V supply voltage  
Rapid soft start after power-on typical within 70 µs  
Simple power adjustment via the external resistor  
Control loop accuracy better than 1% with changes in  
temperature, supply voltage and load current  
Bar-code readers  
Integrated reverse polarity protection for the iC and laser diode  
Strong suppression of transients with very 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 LD types to be used  
(N/P/M configurations)  
PACKAGES  
Modulation via the feedback inputs is possible  
Wide monitor current range from 10 µA to 2.5 mA  
iC-WK with additional spike detection at monitor input MDA  
SO8  
MSOP8
