ATR0881 Datasheet - ATMEL

ATR0881 3-output Laser Driver

The ATR0881 is a laser diode driver designed to operate two grounded red laser diodes for CD and DVD and one floating blue laser diode for Blu-ray. The floating blue laser diode needs an extra supply voltage VH. The serial interface (SPI and TWI supported) makes ATR0881 very flexible and configurabl.

ATR0881 Features

* Two High-side Outputs for Grounded Red Laser Diodes

* Total Output Current up to 700 mA at VLD = 3.8V

* One Low-side Output for Floating Blue Laser Diode

* Total Output Current up to 550 mA, External LD Supply Voltage

* Five Channels with Gain DACs
