ATR0881 Description

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 configurable for a wide range of applications.

ATR0881 Key Features

  • Two High-side Outputs for Grounded Red Laser Diodes
  • Total Output Current up to 700 mA at VLD = 3.8V
