Product description

Six channel laser switch iC-HGP enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 200 MHz. The high-side circuit architecture of the iC-HGP allows the operation of common-cathode laser diode arrays with cathode grounded.

Each channel can be operated up to 500 mA CW and 1500 mA pulsed current depending on the frequency, duty cycle and heat dissipation.


  • Six channel laser switch from CW up to 200 MHz
  • CW operation with up to 500 mA per channel
  • Pulsed operation with up to 1.5 A per channel
  • Spike-free switching of the laser current
  • 6 x 1 channels with TTL inputs
  • 3 x 2 channels with LVDS inputs
  • Operates as six independent voltage-controlled current sources
  • Laser supplies are 12 V capable for blue/green laser diodes
  • Fast and slow switching mode
  • Simple current control at pins CIx
  • CIx voltage < 3 V for full CW current
  • Wide supply voltage range from 3 to 5.5 V
  • All channels can be paralleled for up to 3 A CW and 9 A pulsed operation
  • Multiple iC-HGP can be connected in parallel for higher currents
  • Open drain error output
  • Thermal shutdown


  • TOF camera lighting
  • LIDAR lighting
  • Data transmission
  • Pump lasers
  • Laser projection
