[FAQ] TIDA-01335: How does TIOL111 enable IO-Link connectivity in space constrained ultra-small field transmitters

TIDA-01335 demonstrates the IO-Link communication in a small form factor of just 6mm PCB width with integrated protection and a resistance temperature detector (RTD) sensor front-end.

TIOL111 is a transceiver implementing 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

The TIOL111 comes in a very small form factor allowing the distance sensor to be only 6 mm in width. The Proximity Switch Reference Design TIDA-01239 takes it even further demonstrating a possible width of only 3.5 mm while still being capable of withstanding up to 1.2 kV (500 Ω) of IEC 61000-4-5 surge.

You can also download the design files (BOM, Schematic, Gerber) for the two reference designs from the TIDA-01335 or TIDA-01239 folder.
