Applications
IO-Link is a point-to-point interface between exist-
ing field busses and sensor/actuator devices. IO-Link
serves the transmission of specific parameters or data,
like diagnosis information.
This IC is intended to be used as transceiver in IO-Link
and standard IO mode applications in sensor and ac-
tuator devices. Communication and power supply work
across a common three wire cable to the IO-Link Mas-
ter, so continued use of available wiring is possible.
The integrated voltage regulator provides 5V/20mA
for external purposes. The output driver provides up
to 200mA and features reverse polarity protection plus
over current protection. It can be configured as low side,
high side, or push-pull driver. The switchable slew rate
allows low and optimized electromagnetic radiation.
The tiny package outline allows usage even in applica-
tions with very limited board space.
