Texas Instruments TIOL112x IO-Link Transceivers

Texas Instruments TIOL112x IO-Link Transceivers implement 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 can initiate communication and exchange data with the remote node. At the same time, the TIOL112x acts as a complete physical layer for communication.

These devices can withstand 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. Texas Instruments TIOL112x can be configured to generate a 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.
