iC-HTP 2 channel laser diode driver

iC-HTP new.... two colors with one laser driver

 

The new laser diode driver iC-HTP permits microcontroller-based driving of laser diodes with common cathodes or P-type laser diodes in CW mode (Continuous Wave). With this device either Automatic Power Control (APC), Automatic Current Control (ACC), or a full controller-based power regulation can be used. For driving N-type and M-type laser diodes in CW mode, the similar laser diode driver iC-HT can be used. The maximum laser diode current per channel is 750 mA. Both channels can be connected in parallel for higher laser diode currents of up to 1.5 A. A current limit can also be configured for each channel. Due to the high integration level of the analog functions for driving the laser diodes with a microcontroller interface, multi-channel laser diode control units can be implemented directly. Apart from the iC-HTP only a microcontroller and laser diodes with different wavelengths, for example, are required.

Internal operating points and voltages can be output through analog/digital converters. The integrated temperature sensor permits the system temperature to be monitored and can also be used for feedback in the control circuit. 
Logarithmic digital/analog converters allow optimal power regulation across a large dynamic range enabling a variety of laser diodes to be used.

The relevant configuration is stored in two equivalent memory areas; internal current limits, a supply voltage monitor, channel-specific interrupt switching inputs, and a watchdog secure the operation of the laser diodes through iC-HTP.

iC-HTP uses supply voltages of 2.8 to 11 V and can thereby drive both blue and green laser diodes. Operating temperatures range from -40 to +85 °C. The device is packaged in a 28-pin 5 mm x 5 mm QFN.
