LASER DIODE DRIVER

Rev C1, Page 1/12

FEATURES

APPLICATIONS

♦ Laser diode driver for continuous and pulsed operation (CW to

300 kHz) up to 250 mA

♦ General purpose laser diode

driver

♦ Averaging control of laser power

♦ Simple adjustment of the laser power via external resistor

♦ Adjustable watchdog at the switching input to protect the laser

diode

♦ Soft-start after power-on

♦ Driver shutdown with overtemperature and undervoltage

♦ Single 5 V supply

♦ Simple circuitry

♦ iC-WJ for laser diodes with 50 to 500 µA monitor current

♦ iC-WJZ for laser diodes with 0.15 to 1.5 mA monitor current
