HIP9022
Dual High Speed Laser Driver
The 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.
Eight S/H circuits are multiplex bus controlled to provide
analog data for the dual laser drivers. The bus is updated
during the blanking period of the laser printer scan with a
data rate up to 2.5MHz. A “thermo-electric-cooler” control
circuit provides temperature control of the laser. Two on-chip
ESD diodes protect each laser.
A principle advantage of the Dual High Speed Laser Driver is
accomplished by managing the high currents externally with
discrete Power FETs and thereby not forcing large switching
currents to exist on the same IC substrate with the precision
control circuitry.
