3 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.
