TIOL1125 Übersicht
An IO-Link device transceiver is a physical layer interface IC that enables point-to-point communication between sensors or actuators and an IO-Link master, carrying both power and data over a standard 3-wire cable. As part of the industrial networking and interface IC hierarchy, it integrates drivers, receivers, surge protection, and voltage regulation between the sensor microcontroller and the IO-Link cable.
Key features include an integrated linear regulator (LDO) specified for L+ voltages from 7 V to 36 V with respect to L-, supplying 5 V to external components such as the sensor MCU; a typical residual voltage of only 0.5 V at 200 mA, reducing power dissipation; and a configurable output driver supporting PNP, NPN, or IO-Link modes. Functional-safety-capable documentation is available to support IEC 61508 system design.
The TIOL1125 integrates the C/Q driver and receiver with surge protection per the IO-Link physical layer, reducing external TVS and driver components. Remote wake-up indication and generation plus a configurable current limiter improve robustness and simplify compliance testing. COM1 (4.8 kbps), COM2 (38.4 kbps), and COM3 (230.4 kbps) data rates are supported for flexible system design.
Typical applications include industrial proximity and photoelectric sensors, actuators, valve positioners, and IO-Link device nodes in factory automation and smart manufacturing. The small VSON-10 package suits space-constrained sensor housings, while the wide supply range and integrated protection suit harsh industrial environments.
Design tip: place decoupling close to the L+ and L- pins and the LDO output capacitor near the VCC pin to ensure regulator stability; verify integrated surge protection against your system EMC test levels.

Typische Anwendungen
TIOL1125 ist geeignet für 6 Anwendungs: IO-Link Industrial Proximity Sensors, Photoelectric Sensor IO-Link Nodes, Actuators and Valve Positioners, Factory Automation IO-Link Masters and Device Networks, Condition Monitoring and Smart Sensor Retrofits, Functional-Safety-Oriented Sensor Systems.
IO-Link Industrial Proximity Sensors
The TIOL1125 fits inductive and capacitive proximity sensor IO-Link nodes because its C/Q driver supports PNP, NPN, and IO-Link modes with IEC 61131-9 COM1/COM2/COM3 rates, letting one hardware platform serve both standard and IO-Link sensor variants. The integrated surge protection and 36-V tolerant supply handle industrial cable transients without external TVS diodes, and the 0.5-V typical residual voltage at 200 mA reduces on-board dissipation in compact sensor housings. The 5-V LDO powers the sensor MCU directly from the L+ line, eliminating a separate regulator.
Empfohlen
Photoelectric Sensor IO-Link Nodes
Photoelectric sensors benefit from the TIOL1125's configurable current limiter and remote wake-up generation, which are required for IO-Link device compliance testing. The COM3 (230.4 kbps) support allows fast parameter and process-data exchange with the IO-Link master, while the functional-safety-capable documentation aids machine-level safety assessments. The VSON-10 (3x3 mm) footprint is small enough for tight optical-head PCBs, and the 7-V to 36-V L+ range tolerates cable-drop variations in long sensor runs on factory floors.
Empfohlen
Actuators and Valve Positioners
For pneumatic valve positioners and small actuators, the TIOL1125 provides a robust PNP/NPN output stage with configurable current limiting, protecting the driver during stall or short-circuit events on the actuator line. The integrated LDO (5 V, 7-V to 36-V input) supplies the position-feedback electronics from the same 3-wire IO-Link cable that carries data, simplifying wiring. Low residual voltage reduces heat in sealed enclosures where convection cooling is limited, improving long-term reliability of the actuator drive stage.
Empfohlen
Factory Automation IO-Link Masters and Device Networks
In smart-manufacturing networks, every IO-Link device port needs a robust physical layer. The TIOL1125 complies with IEC 61131-9 for COM1 through COM3, so a single device design interoperates with any compliant master. Integrated surge protection simplifies EMC qualification of dense multi-port master or device boards, and the 0.5-V residual voltage lowers per-node power loss when dozens of devices share a cabinet supply. Pin compatibility with TIOL111 enables cost-optimized BOM migration across product generations.
Empfohlen
Condition Monitoring and Smart Sensor Retrofits
Retrofitting legacy 3-wire PNP/NPN sensors with IO-Link capability is a common Industry 4.0 upgrade path. The TIOL1125 supports both legacy discrete output modes and IO-Link communication on the same hardware, so one PCB serves old and new installations. Remote wake-up indication lets the sensor sleep between measurements, cutting average power draw, while the LDO output powers the added intelligence (MCU plus MEMS sensor). Wide L+ tolerance absorbs unregulated plant supply variation during retrofit deployments.
Empfohlen
Functional-Safety-Oriented Sensor Systems
The TIOL1125 is functional-safety-capable with documentation available to aid IEC 61508 system design, making it appropriate for safety-related sensor nodes such as light curtains, safety interlocks, and emergency-stop position feedback. Deterministic IO-Link communication at COM2 or COM3 with wake-up support enables safe parameterization and diagnostics. The integrated current limiter and surge protection reduce the external component count that would otherwise need individual safety analysis, shortening the system-level safety assessment cycle.

- Integrated 5-V LDO (vs. TIOL111)
Designhinweise
Place a decoupling capacitor close to the L+ and L- pins and the LDO output capacitor near the VCC pin to ensure regulator stability across load transients. Keep the C/Q trace short and route it away from sensitive analog signals to minimize coupling during COM3 (230.4 kbps) communication. The VSON-10 exposed pad should be soldered to a ground pour for thermal and EMC performance.
Do not exceed the 36-V maximum L+ voltage; unregulated industrial 24-V supplies can spike well above nominal during load dumps, so verify the integrated surge protection covers your system EMC test levels (surge, burst, ESD per IO-Link test specification) before skipping external TVS diodes entirely. Confirm the LDO output (5 V on TIOL1125 vs 3 V on TIOL1123) matches your MCU supply before substituting family members.
The 0.5-V typical residual voltage at 200 mA reduces on-state dissipation to about 0.1 W in the driver, but total budget must include LDO dropout from L+ to 5 V. At 24-V L+ and 50-mA LDO load, the device dissipates roughly 0.95 W - use the exposed pad and at least 2x2 via fanout to the ground plane to keep junction temperature within limits in sealed sensor housings.
The configurable current limiter setting resistor should be placed close to the I_SET pin with a low-impedance ground return to avoid false limiting during COM3 drive transitions. If wake-up signaling is used, keep the EN/wake-up trace away from the C/Q line to prevent spurious wake-up from cable transients.
