ATR1841

1. Description

The ATR1841 is a front monitor diode (FMD) which controls the laser power of the

optical pickup for Blu-ray/HD-DVD, DVD and CD drives in one IC.

Summary

Preliminary

With the Two-wire Interface (TWI) it is possible to fit the laser power for

Blu-ray/HD-DVD, DVD and CD. Two bits are used to set the mode/gain level and 6

additional bits are used for gain trimming, within ±6 dB. Entering sleep mode is also

controlled via the TWI.

The integrated PIN diode and the high speed amplifier with low output impedance

ensures stable driver performance.

All output channels are set to tri-state during sleep mode.

Due to its small package size the ATR1841 is especially suited for applications with

low height requirements like SLIM and Ultra-SLIM drives.
