Description
Laser diode pulse driver iC-NZN allows CW operation of laser diodes and spike-free switching with defined current pulses up to 155 MHz. The optical output power of the laser diode is set-up by means of an external resistor (RMD/PMD). For laser current control without a monitor diode, the laser current monitor at pin IMON is utilised. For high pulse frequencies the device can be switched into controlled burst mode. A previously settled operating point is maintained throughout the burst phase. An averaging current monitor can be set by means of an external resistor at pin RSI. When the current limit is reached, overcurrent is signalled at NERR and the current from pin LDA is limited to the pre-set value but the iC is not shut down. There is an additional current limitation in pin LDK that prevents the iC from overpowering the laser diode. Setting pin NSLP low, the iC enters a low consumption sleep-mode (< 50 ìA typ.).
