RH4Z2501BJ3GNM#HD0 Übersicht
An IO-Link physical layer (PHY) transceiver is a dedicated interface IC that implements the IEC 61131-9 single-drop digital communication interface for industrial sensors and actuators. The PHY sits between the microcontroller UART/IO-Link stack and the 3-wire sensor cable (L+, L-, CQ), handling 24 V line drive levels, reverse-polarity protection, surge suppression, and the 8 mA / 16 mA / 24 mA current-sinking modes defined by the IO-Link standard. It belongs to the hierarchy: IO-Link PHY -> industrial transceiver -> interface IC -> integrated circuit -> semiconductor.
Key features include configurable CQ output stages (push-pull, high-side, low-side), integrated reverse-polarity blocking on the supply pin, 60 V transient robustness on L+, an OWI (One-Wire Interface) configuration channel for parameter storage, and CMOS mixed-signal technology that supports 4.5 V to 30 V supply operation. The 12-DFN package offers a compact 3x3 mm footprint for space-constrained sensor heads.
The RH4Z2501 includes internal protection features that simplify the external TVS/Schottky network typically required by IO-Link designs: over-temperature shutdown, under-voltage lockout, and reverse-polarity handling. The OWI channel allows the MCU to write configuration and identification data to on-chip non-volatile memory during end-of-line commissioning.
Typical applications include IO-Link sensor signal conditioning in factory automation, IO-Link master communication modules, 24 V industrial valve and actuator drivers, and PLC digital I/O cards implementing single-drop IO-Link ports.
When designing with this part, place the decoupling capacitor (10 V on L+) as close to the pin as possible and keep the CQ trace short to minimize radiated EMI. Configure the OWI address during manufacturing only - do not reconfigure OWI in the field without a controlled procedure.

IO-Link Sensor Signal Conditioning
The RH4Z2501BJ3GNM#HD0 sits between a sensor MCU and the 3-wire IO-Link cable, providing the 24 V line drive levels defined by the IEC 61131-9 physical layer. Its push-pull CQ driver delivers IO-Link's 8 mA / 16 mA / 24 mA current-sink modes with RDS(ON) below 2.5 ohm, ensuring clean signal edges and meeting the standard's timing masks. Integrated reverse-polarity protection on L+ eliminates the external diode bridge typically needed, reducing BOM and board area in smart sensor heads.
Empfohlen
IO-Link Master Communication Module
As a single-channel master transceiver, the RH4Z2501BJ3GNM#HD0 enables a host MCU to drive an IO-Link master port with the correct 24 V swing and protection. Its OWI configuration channel allows end-of-line programming of master port parameters (current limit, revision, vendor ID), simplifying commissioning. The 60 V transient tolerance on L+ lets the master port ride through cable discharge events without an external TVS, which is critical for factory-floor installations.
Empfohlen
24V Industrial Valve and Actuator Driver
The RH4Z2501BJ3GNM#HD0 is well suited for driving 24 V solenoid valves, pneumatic actuators, and binary I/O blocks via IO-Link. Its push-pull CQ output can directly switch an external low-side MOSFET to drive inductive loads, while integrated over-temperature and under-voltage lockout protect the actuator line. The 12-DFN (3x3 mm) footprint enables compact valve-manifold electronics where PCB real estate is at a premium.
Empfohlen
PLC Digital I/O Card with IO-Link Port
Inside a PLC or remote I/O module, the RH4Z2501BJ3GNM#HD0 provides the physical-layer termination for a single IO-Link port on the field-side connector. Its 4.5 V to 30 V supply range handles common 24 V industrial rails, and the integrated protections reduce the need for external surge and reverse-polarity components. A single MCU can poll multiple RH4Z2501 devices via separate OWI channels for multi-port cards.
Empfohlen
IO-Link Photoelectric and Proximity Sensor
Photoelectric, inductive, and capacitive proximity sensors increasingly adopt IO-Link for remote configuration and diagnostics. The RH4Z2501BJ3GNM#HD0's 12-DFN (3x3 mm) package fits in the cylindrical M12/M18 sensor housing PCB alongside the photo-detector front-end. Its low quiescent current and integrated protections make it ideal for sensors that must operate continuously on the 24 V IO-Link rail without dissipating excess heat.
Empfohlen
Industrial Robot End-Effector IO
Robotic grippers and tool changers use IO-Link to exchange status, tool-data, and actuator commands over a 3-wire M12 cable. The RH4Z2501BJ3GNM#HD0's 60 V transient rating and integrated reverse-polarity handling survive the ESD and surge events common on moving cables. The OWI channel can store end-effector ID and calibration data locally, enabling automatic tool recognition by the robot controller.
Empfohlen
Smart Industrial Lighting Controller
Addressable industrial LED light towers and machine-status indicators increasingly adopt IO-Link for configuration. The RH4Z2501BJ3GNM#HD0 acts as the IO-Link device-side transceiver, letting the master PLC upload color sequences, brightness profiles, and diagnostic thresholds. The integrated protection chain tolerates wiring errors during field installation in harsh industrial cabinets.

Wichtigste Unterscheidungsmerkmale
- 60 V transient tolerance with integrated reverse-polarity block (vs. Discrete 24 V IO-Link driver + external TVS)
- OWI configuration channel with on-chip NV memory (vs. MAX22515 I2C/SPI configuration)
- Same silicon supports both master and device roles (vs. Single-role dedicated ICs (e.g., LT3669 device-only))
Designhinweise
Place a 10 V ceramic decoupling capacitor on L+ as close to pin 1 as possible, with a 100 nF X7R bypass on VDD (pin 10) within 2 mm. Solder the exposed pad (pin 12) to a continuous ground copper pour of at least 10 mm^2 to meet the thermal resistance target. Keep the CQ trace shorter than 50 mm and avoid routing near switching converter nodes to preserve IO-Link signal edges.
Do not omit the reverse-polarity protection diode on L+ even though the part integrates it - the integrated block handles sustained reverse polarity, but external TVS is still recommended for surge events beyond 60 V. Always configure the OWI address during end-of-line test only; reconfiguration on the field requires a controlled procedure to avoid bricking the device's NV memory.
Estimated: at 24 V supply and continuous CQ switching at 24 mA IO-Link high-current mode, the part dissipates roughly (24 V - Vload) * 0.024 W in the low-side FET. For a 12-DFN package with theta_JA around 50 C/W on a 1 oz 4-layer PCB, this yields a ~10C temperature rise - well within the 125C operating limit. Provide additional copper pour if the application sustains 50+ mA combined drive current.
The CQ line must be terminated at the receiver per the IO-Link cable specification (typically 1 nF to ground). Keep the L+/L- pair routed as a differential pair to minimize EMI pickup from adjacent relay or motor cables. For CE-marked industrial equipment, add a common-mode choke on the CQ line if cable length exceeds 5 m.
Compliance-Informationen
