Product Information

Back to top
The power CW laser diode driver iC-HTG provides Automatic Current (ACC) or Power (APC) Control functionality operating an external scalable driver. For APC the programmable logarithmic monitor resistor ranges from 100? to 500 k? at a step width <4%. The logarithmic D/A converter sets the operating point better than 1%. A wide range of laser diode current can be measured and controlled (APC) by a shunt resistor. An analog modulation with a frequency of up to 50 kHz is possible. Overcurrent, overtemperature, or standby will disable the laser. All parameters, chip temperature, and all system related voltages are accessible via serial communication (I²C or SPI). An external DC/DC converter can be controlled to optimize the total power dissipation.

Symmetry Electronics is an authorized iC-Haus distributor.
