Product Overview

The 2011658 is a Laser Diode Driver for continuous wave operation which requires only 4 external components. The wide supply range of 2.4 to 6V and the integrated reverse battery protection allow for battery operation with a minimum of 2 cells. A reversed battery connection destroys neither the IC nor the laser diode. The IC includes integrated circuitry protecting against destruction by ESD, excessive temperature and over current and a soft start which regulates the power supply is switched on. The IC also filters the laser diode power supply for transients. The power supply is regulated and adapted to the laser diode used by an external resistor at MDA. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage. The capacitor at CI determines the control time constants and start-up time.
  • Rapid soft start after power-on typical within 70μs
  • Simple power adjustment via external resistor
  • Control loop accuracy better than 1% with changes in temperature, supply voltage and load current
  • Integrated reverse polarity protection for IC and laser diode
  • Strong suppression of transients with very small external capacitors, integrated flyback path
  • Permanent shut down with excessive temperature and overcurrent
  • 2 Feedback inputs permit all current LD types to be used
  • Modulation via feedback inputs is possible
  • Wide monitor current range from 10μA to 2.5mA
  • iC-WK with additional spike detection at monitor input MDA
