3 Description
The TIOL112(x) family of transceivers implements the
IO-Link interface for industrial bidirectional, point-topoint
communication. When the device is connected
to an IO-Link master through a three-wire interface,
the master initiates communication and exchange
data with the remote node while the TIOL112(x) acts
as a complete physical layer for the communication.
These devices are capable of withstanding up to
1.2 kV (500 Ω) of IEC 61000-4-5 surge and feature
integrated reverse polarity protection. A simple pinprogrammable
interface allows easy interfacing with
the controller circuits. The output current limit can
be configured using an external resistor. TIOL112(x)
can be configured to generate wake-up pulse and be
used in IO-link master applications. Fault reporting
and internal protection functions are provided
for undervoltage, overcurrent and overtemperature
conditions.
