The SN65HVD101 implements the IO-LINK interface for industrial 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 SN65HVD10X acts as a complete physical layer for the communication. The IO-LINK driver output (CQ) can be used in push-pull, high-side, or low-side configurations using the EN and TX input pins. The PHY receiver converts the 24-V IO-LINK signal on the CQ pin to standard logic levels on the RX pin. A simple parallel interface is used to receive and transmit data and status information between the PHY and the local controller. The SN65HVD101 implements protection features for overcurrent, overvoltage and overtemperature conditions. The IO-Link driver current limit can be set using an external resistor. The SN65HVD102 operates from a single external 3.3-V or 5-V local supply. The SN65HVD101 integrates a linear regulator that generates either 3.3 V or 5 V from the IO-Link L+ voltage. The SN65HVD101 is available in the 20-pin RGB package (4 mm × 3,5 mm QFN) for space-constrained applications.
