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 conditions.
The HY6340 comes in a 22 pin dual in-line ceramic
package. An aluminum heat spreader is included as a
part of the package for heat sinking the device.
Features:
✦ Analog input, DC to 1MHz
✦ Adjustable modulation current to 1.5 amps
✦ Patented “backmatched” thermal
management
✦ Enable pin for switching
✦ Overtemp and over-current alarms
✦ Common anode isolated laser diodes
✦ Thru-hole or surface-mount packaging
