PRELIMINARY

Dual High Speed Laser Driver

Features

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.

• Dual High Speed Laser Driver with Data Rates up to

2.5MHz

• 0.5A to 2A Range of Constant Current Source Controlled

to 0.1% Full Scale

• Low Signal Transients with Controlled Constant Current

Switching

• Laser Optical Power Controlled to Better than 0.5%

• Thermoelectric Cooler (TEC) Circuit to Control

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.

Temperature to within 0.25 C

• Multiplexed Sample/Hold (S/H) Bus Interface

• Serial Diagnostic Bus with Multiplexed Output

• High Current ESD Diodes for Laser Diode Protection

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.

Applications

• Dual Laser Printer Driver
