Data Sheet
Safety hints
Application of new chip technologies leads to increasing optical efficiency and
growing and higher levels of optical performance.
We therefore recommend that the current versions of the IEC 825-1 and EN 60825-1
standards are taken into account right from the outset, i.e. at the equipment
development stage, and that suitable protection facilities are provided.
1. Short description of complete functional unit
The device consists of a LED mounted on a large area photodiode for bidirectional optical transmission
in half duplex mode. LED and photodiode are driven by the multifunction IC E100.34C1 from ELMOS.
The transmitting and receiving functional units with ELMOS-IC E100.34C1 may be split into the
following blocks:
VDD2
GND
VDD1
DO
Transmitter
LED Driver
LED
LEDO
L^PE^DD^I I
DI
ALARM
Receivingamplifier
