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.
