Product description

The iC-WK/L device is a driver for laser diodes in continuous wave operation which requires only four external components. The wide power supply range of 2.4 to 6 V and the integrated reverse battery protection allow for battery operation with a minimum of two cells.

The iC includes a soft start which regulates the power and protects the laser diode when the power supply is switched on. The iC also filters the laser diode power supply for transients.

Features

  • iC-WK MSOP8 AEC-Q100 qualified (Grade 3)
  • CW operation up to 90 mA from 2.4 to 6 V supply voltage
  • Fast 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
  • 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)
  • Modulation via the feedback inputs is possible
  • Wide monitor current range from 10 µA to 2.5 mA
  • Additional spike detection at monitor input MDA

Applications

  • Battery-powered LD modules
  • LD Pointers
  • Laser levels
  • Bar-code readers
