IO-Link device transceivers with integrated surge protection

The TIOL111 family of transceivers, from Texas Instruments, 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 can initiate communication and exchange data with the remote node while the TIOL111 acts as a complete physical layer for the communication. These devices are capable of withstanding up to 1.2kV (500ohm) of IEC 61000-4-5 surge and feature integrated reverse polarity protection. A simple pin-programmable interface allows easy interfacing to the controller circuits. The output current limit can be configured using an external resistor. Fault reporting and internal protection functions are provided for under voltage, over current and over temperature conditions.
