Product Information

Dual CW laser diode driver iC-HT can operate two individual laser diodes with up to 750 mA laser current depending on the heat dissipation.  Each channel can be enabled independently.  The laser diode driver can be controlled by an external microcontroller (MCU mode) or operate stand alone with pin/resistor configuration (iC-WK mode).  In MCU mode, both channels can be combined for driving up to 1500 mA.

Each channel can be opperated individually either in automatic current control (ACC) or automatic power control (APC).  All parameters including the internal reference voltages are set via serial communication.  A 10 bit resolution D/A converter with logarrithmic characteristics is used for setting the opperating point.  This allows an operating point resolution better than 1%.
