L6364Q Visão geral
As an IO-Link PHY, the L6364Q is a bridge transceiver (interface IC) positioned in the industrial-sensor signal chain: MCU -> IO-Link transceiver -> 24 V cable -> IO-Link master. It supports M-sequence handling, wake-up pulse generation, and SPI configuration from the host microcontroller so the device can be reused across discrete sensors, actuators, and binary (SIO) legacy modes.
Key features include a wide 8 V to 36 V operating supply range compatible with industrial 24 V rails, integrated reverse-polarity and over-current protection on the high-side drivers, two independent CQ channels, dual LDO regulators (3.3 V and 5.0 V at 50 mA each) for host MCU supply, integrated DC-DC converter, and -40 C to +150 C extended industrial temperature range. The 20-pin QFN (4x4 mm) package minimizes PCB area for space-constrained sensor heads.
Internally the L6364Q combines two C/Q output drivers with current limiting, two LDO regulators with power-good indication, a DC-DC controller for energy-efficient 24 V-to-low-voltage conversion, and an SPI interface for M-sequence parameterization. Compared with discrete IO-Link implementations, the L6364Q shrinks the BOM by replacing multiple protection devices, regulators, and the DC-DC passives with one qualified IC.
Typical applications include industrial binary sensors and proximity switches, factory automation actuators with IO-Link connectivity, IO-Link sensor hubs and junction boxes, smart valve and valve-position feedback modules, robotics I/O modules, and process-control instrumentation. The wide input voltage range and integrated protection suit 24 V factory bus operation, while the dual channels enable single-chip two-port sensor nodes.
When designing with this part, ensure that thermal management of the QFN exposed pad is adequate - the dual LDO currents plus DC-DC losses can produce 500 mW dissipation at full load. Use the SPI interface to switch from SIO mode to IO-Link mode dynamically without disturbing the in-progress IO-Link communication frame.

Aplicações típicas
L6364Q é adequado para 6 aplicaçãos: Industrial Binary Sensor / Proximity Switch, IO-Link Sensor Hub / Junction Box, Smart Valve / Valve Position Feedback Module, Factory Automation Actuator with IO-Link, Process Control Instrumentation Transmitter, Robotic I/O Module (IO-Link slaves).
Industrial Binary Sensor / Proximity Switch
The L6364Q's dual C/Q channels and integrated 3.3 V/5.0 V 50 mA LDOs directly drive industrial 24 V binary (SIO) proximity sensors and photoelectric switches without external regulator stages. Operating from 8 V to 36 V it tolerates factory-bus transients, while the integrated reverse-polarity and over-current protection on the high-side drivers eliminate external TVS and fuse components. Placed between the host MCU and the M12 sensor connector, it provides one-chip PHY + power management for a typical IO-Link sensor head.
Recomendado
IO-Link Sensor Hub / Junction Box
Two independent C/Q channels make the L6364Q ideal for two-port IO-Link sensor hubs that aggregate multiple field devices onto one master port. Each channel can host a separate IO-Link slave while sharing the integrated DC-DC converter and SPI configuration bus. The -40 C to +150 C temperature grade supports cabinet- or field-mounted hub installations where ambient temperatures and self-heating from many ports in a small enclosure would stress commercial-grade ICs.
Recomendado
Smart Valve / Valve Position Feedback Module
Valve-position feedback modules require robust 24 V IO drivers plus clean low-voltage rails for the MCU and angle-sensor signal chain - exactly what the L6364Q integrates. The two channels can drive the actuator coil and read back the position sensor through the same C/Q pins in IO-Link mode. The DC-DC converter supplies a stable rail to op-amps used for position-sensor amplification, while the integrated reverse-polarity protection prevents field-wiring mistakes from damaging the module.
Recomendado
Factory Automation Actuator with IO-Link
Industrial actuators - pneumatic cylinders, rotary drives, grippers - increasingly embed IO-Link for diagnostics and parameter upload. The L6364Q handles the 24 V power/signal interface while the host MCU runs the actuator's local logic. Wide supply headroom (8 V to 36 V) absorbs the back-EMF and cable voltage drops common in factory wiring, and the 50 mA LDO budgets size the host MCU on each actuator node without external regulators.
Recomendado
Process Control Instrumentation Transmitter
Process-control transmitters measuring pressure, level, or flow commonly use IO-Link for parameter upload and remote diagnostics. The L6364Q's integrated LDO and DC-DC reduce total BOM for the compact head-mounted transmitter form factor, while its -40 C to +150 C range supports outdoor installations. Place the L6364Q between the 4-20 mA/IO-Link hybrid module and the microcontroller to offload the IEEE 802.15.4/everything-to-bridge 24 V IO layer.
Recomendado
Robotic I/O Module (IO-Link slaves)
Modular robotics peripherals - tool changers, vacuum gripper sensors, end-effector diagnostics - increasingly use IO-Link for plug-and-play commissioning. The L6364Q's small 4x4 mm QFN package fits tight robotic-joint enclosures, and its integrated regulators remove the need for bulky external power conditioning. The dual channels can service both an actuator drive and a sensor readback from the same small module, minimizing harness complexity in robotic cells.

Principais diferenciais

- Industrial-grade thermal range (vs Commercial-grade IO-Link companion ICs)
Notas de projeto
The L6364Q's 20-QFN (4x4 mm) exposed thermal pad carries significant heat under full dual-channel, full-load IO-Link operation. Estimated: with both 50 mA LDOs at 5.0 V from a 24 V supply plus DC-DC losses, total dissipation can reach approximately 500 mW (24 V - 5 V) x 50 mA x 2 plus DC-DC switching losses. Solder the exposed pad to a copper pour of at least 1 square inch on top and bottom layers to keep junction temperature within the -40 C to +150 C operating range.
Follow ST's recommended layout in the L6364 datasheet: place input capacitors as close as possible to the VS pin, route the DC-DC switching node (SW) over a short trace on the top layer, and keep the SPI signals away from the switching node to avoid coupling. For EMC compliance with the IO-Link IEC 61131-9 specification, use sufficient bulk capacitance on VS and filter components on the C/Q lines as documented in the ST X-NUCLEO-IOD02A1 expansion-board schematic.
Do not leave the exposed thermal pad of the 20-QFN unsoldered - it is electrically required for ground and thermally critical for power dissipation. Avoid running the C/Q lines in parallel with the DC-DC switching node for long distances to prevent conducted noise from coupling into the IO-Link signal. M-sequence parameter configuration via SPI must complete before the host MCU initiates IO-Link communication; failing to do so leaves CQ channels in default SIO mode.
