IC-VJ Datasheet, PDF (1/10 Pages) IC-Haus GmbH – LASER DIODE CONTROLLER

iC-VJ, iC-VJZ
LASER DIODE CONTROLLER
FEATURES
o Laser diode driver of up to 250 mA
o Averaging control of laser power
o Protective functions to prevent destruction of laser diode
o Laser-current monitor with current or voltage output
o Integrated RC oscillator up to 4 MHz
o Integrated 16:1 divider for pulse generation in the kHz range
o Stable 1:1 pulse duty ratio
o Simple adjustment of the laser power via external resistor
o Soft-start at power-on
o Complementary pulse repetition frequency output for ECL level
o Shutdown in case of overtemperature
o Single 5 V power supply
o Very few external components
o iC-VJ for laser diodes with 50 to 500 µA monitor current
o iC-VJZ for laser diodes with 0.15 to 1.5 mA monitor current
Rev A1, Page 1/10
APPLICATIONS
o Transmitter for laser light barri-
ers from 1 to 200 kHz
