iC-NZN
N-TYPE LASER DIODE DRIVER
FEATURES
o Peak value controlled laser diode driver for operation from CW
up to 155 MHz
o Spike-free switching of laser currents of up to 300 mA
o Setting of laser power (APC) via external resistor
o Optional current control (ACC)
o Laser current limitation
o LVDS/TTL switching input with TTL monitor output
o Low current consumption sleep-mode < 50 µA
o Safety shutdown with overtemperature
o Error signal output with overtemperature, undervoltage and
overcurrent
o All current LD types can be used (N/P/M configurations)
o Blue laser diodes supported
o Fast soft-start
o Strong suppression of transients with small external capacitors
Rev C1, Page 1/17
APPLICATIONS
o Pulsed and CW laser diode
modules
o Laser diode pointers
o Laser levels
o Bar-code readers
o Distance measurement
o Blue laser diodes
