The TIOL112x family of transceivers implements the IO-Link interface for industrial bidirectional, point-to-point 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 TIOL112x acts as a complete physical layer for the communication.

These devices are capable of withstanding up to 1.2kV (500Ω) of IEC 61000-4-5 surge and feature integrated reverse polarity protection. A simple pin-programmable interface allows easy interfacing with the controller circuits. The output current limit can be configured using an external resistor. TIOL112x devices 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.

TIOL112 or TIOL112x transceivers implement protection features for overcurrent, overvoltage, and overtemperature conditions. The devices also provide a current-limit setting of the driver output current using an external resistor.

The devices derive the low-voltage supply from the IO-Link L+ voltage (24V nominal) via an internal linear regulator to provide power to the local controller and sensor circuitry.
