DESCRIPTION
The SN65HVD101 and ‘HVD102 IO-LINK PHYs implement the IO-LINK interface for industrial point-to-point
communication. When the device is connected to an IO-Link master through a 3-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 and 'HVD102 implement protection features for overcurrent, overvoltage and overtemperature
conditions. The IO-Link driver current limit can be set using an external resistor. If a short-circuit current fault
occurs, the driver outputs are internally limited, and the PHY generates an error signal (SC). These devices also
implement an overtemperature shutdown feature that protects the device from high-temperature faults.
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 for supplying power to the PHY as
well as a local controller and additional circuits.
The SN65HVD101 and 'HVD102 are available in the 20-pin RGB package (4 mm × 3,5 mm QFN) for space-
constrained applications.
