The new laser diode driver iC-HT, from iC-Haus GmbH, permits microcontroller-based activation of laser diodes in CW mode.

With this device laser diodes can be driven by either the optical output power (using APC), the laser diode current (using ACC), or a full, controller-based power control unit.

The maximum laser diode current per channel is 750 mA. Both channels can be switched in parallel for particularly high laser diode currents of up to 1.5 A.   A current limit can also be configured for each channel.

Thanks to the high integration level of the analog functions for activation of the laser diodes with the microcontroller interface, multichannel laser diode control units can be implemented directly. Apart from the iC-HT, only the microcontroller and laser diodes are required, the latter with varying wavelengths, for example.
