描述 Description

Dual High Speed Laser DriverThe HIP9022 Dual High Speed Laser Driver is designed to operate with a constant current drain from the power supply. This current defines the laser operating power. The current is accurately controlled in the range of 0.5A to 2A to deliver constant optical power from the laser when used with an external Power FET and Power Sense resistor. The operating circuit allows flexibility in choosing driver current levels.
