Product details
Overview
L6360 from STMicroelectronics is an IO-Link master transceiver IC compliant with PHY2 (3-wire) and supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud) modes. It integrates programmable high-side/low-side/push-pull C/QO output stages (< 2 Ω RON), 500 mA L+ protected high-side driver, fast-mode I²C interface (400 kHz), dual diagnostic LED sequencer, and 3.3 V/5 V linear regulator - deployed in industrial sensor nodes for bidirectional data exchange over standard M12 cables.
For engineers reviewing the L6360 datasheet, L6360 pinout, L6360 application, or L6360 equivalent, this page delivers verified technical context on IO-Link PHY2 transceiver operation, programmable cut-off current (70–720 mA), thermal shutdown (150 °C), L+ demagnetization energy handling (10 mJ), and register-level diagnostic access via I²C - critical for factory automation system integration and fault-resilient sensor port design.
Technical Context
The L6360 implements a fully integrated IO-Link master port with dual-channel digital interface: C/QI/C/QO handles physical layer communication (PHY2), while OUTC/Q and OUTI/Q provide isolated logic-level outputs synchronized to host USART framing. Its internal 9-register I²C map enables real-time configuration of cut-off current (70–720 mA), delay timing (100–250 μs), restart behavior (255× delay), and LED diagnostic sequences.
It features dual protection architecture: per-output current limiting (500–1600 mA) combined with programmable cut-off thresholds, plus system-level monitoring of L+ line voltage (9–12 V window), linear regulator undervoltage (3.22–5.13 V), junction temperature (150 °C shutdown / 130 °C restart), and parity errors - all reported via status register bits and open-drain IRQ assertion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IO-Link master transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14824 | Single 24 V L+ output (no dual LED sequencer); supports only COM1/COM2; requires external 3.3 V LDO | Lacks COM3 mode and integrated regulator - suitable for cost-sensitive COM2-only nodes where LED feedback is handled externally | Select when COM3 speed is unnecessary and board space permits discrete LDO + LED driver |
| TMR112 | Integrated 3.3 V LDO and single LED driver; no L+ switch; supports COM1/COM2 only; no I²C register interface | Fixed-function device with minimal configuration - suited for simple point-to-point sensor links without diagnostics | Choose for basic plug-and-play IO-Link connections where register-level control and L+ power delivery are not required |
Compared with MAX14824 and TMR112, the L6360 uniquely combines COM3 speed, integrated 3.3/5 V regulation, dual programmable LEDs, and full I²C-accessible diagnostics - making it optimal for intelligent, multi-sensor industrial gateways requiring field-upgradable configuration and visual status.

FAQ
What IO-Link communication modes does the L6360 support?
The L6360 supports all three standard IO-Link physical layer modes: COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud), enabling compatibility with legacy and next-generation sensors. Mode selection is handled automatically by the PHY2 interface based on sensor handshake; no software configuration is required for basic operation.
How is the L+ output protected against short circuits and inductive kickback?
The L+ output features dual-layer protection: programmable cut-off current (480–730 mA) with adjustable delay (500 μs), plus thermal shutdown at 150 °C. For inductive loads, it safely absorbs up to 10 mJ of demagnetization energy without external components, verified per IEC61000-4-5 surge testing conditions.
Can the L6360 drive two IO-Link sensors simultaneously?
No - the L6360 is a single-port IO-Link master transceiver. Each device manages one C/QI–C/QO pair and one L+ output. To support multiple sensors, multiple L6360 ICs are used, with SA0–SA2 pins configuring unique I²C addresses (up to 8 per bus) for centralized microcontroller control.
What is the function of the Rbias pin, and how is its value determined?
Rbias sets precision bias currents for internal comparators and regulators. A 124 kΩ ±0.1% resistor is specified (Table 3), directly affecting cut-off current accuracy (±1.3%), delay timing (±2.4%), and input current (±1.1%). Deviation beyond tolerance degrades diagnostic repeatability and may cause false fault triggers under marginal conditions.
