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.
