The TIOL221 transceiver integrates dual low-power output drivers with active reverse polarity protection. When the device is connected to an IO-Link controller through a three-wire interface, the controller can initiate communication, and exchange data with the remote node while the TIOL221 acts as a complete physical layer for the communication. The device also integrates an auxiliary DI channel.

The device is capable of withstanding up to 1.2kV (500Ω) of IEC 61000-4-5 surge and features integrated reverse polarity protection. In addition to the SPI interface for configurability and expanded diagnostic capability, a simple pin-programmable interface allows easy interfacing with the controller circuits. The output current limit can be configured using either an external resistor or per-configured limits via SPI interface. TIOL221 can be configured to generate wake-up pulse, and be used in IO-link controller applications. Fault reporting and internal protection functions are provided for undervoltage, overcurrent and overtemperature conditions.
