HY6340 Datasheet (Hytek) - Switchable Constant Current Laser Diode Driver

HY6340, Switchable Constant Current Laser Diode Driver

VEE GND MOD Input power supply ( *9 to *15 VDC).

Ground return for VEE (input power supply) The modulation voltage programs the laser diode drive current, IOUT.

When the input is at VEE the modulation current is zero.

Maximum modulation current occurs when the voltage at MOD is +5.0

www.DataSheet4U.com HY6340 Laser Diode Driver Switchable Constant Current Laser Diode Driver The HY6340 Laser Diode Driver is designed for applications requiring high constant current drive for the operation of laser diodes such as pump sources for EDFA's and diode pumped semiconductors.

The HY6340 provides selectable drive current from zero to 1 ampere (1.5 amperes with forced air cooling).

The HY5640 includes outputs for monitoring and control of over-current and laser diode over-temperature
