The new laser diode driver iC-HT allows the microcontroller-based operation of two cw laser diodes. The optical output power can be controlled via APC (automatic power control), ACC (automatic current control), or a microcontroller.
The maximum operating current per channel is 750 mA or 1.4 A cascaded. An individual limit for each channel is possible in case the laser diodes have to be operated at a lower maximum operating current.
The integration degree of the analog functions is high in case the microcontroller interface is used for the operation of the laser diodes: multi-channel laser diode controllers can be directly implemented this way.
