MAX22513ATI+ Visão geral
An IO-Link device transceiver is a mixed-signal interface that sits between an industrial sensor/actuator and an IO-Link master, handling the IEC 61131-9 physical layer: the C/Q line carries the wake-up pulse, the COM1/COM2/COM3 framed communication, and the high-current switching output; DO/DI provides an auxiliary digital channel. IO-Link transceivers belong to the broader category of industrial sensor interfaces -> more generally to line drivers/receivers -> and finally to wired communication ICs, which are themselves a subset of mixed-signal semiconductors used in factory-automation networks.
Key differentiating features include: an integrated high-efficiency step-down DC-DC converter that generates the 5V or 3.3V logic rail directly from the 24V industrial bus, eliminating an external switching IC; reverse-voltage, short-circuit, and surge protection on all four IO pins; very low on-resistance C/Q and DO/DI drivers; selectable driver current limits to match load requirements; and low quiescent current for IEC 61131-9 sleep/wake behavior. The selectable interface (SPI or pin-strapped logic) lets the same silicon serve multiple microcontroller families. The 28-TQFN-EP package has an exposed pad that drops θJA low enough to dissipate the buck regulator's thermal load without an external heatsink at typical 24V→5V/200mA operating points.
Typical applications include 24V industrial sensor heads (photoelectric, proximity, ultrasonic), IO-Link valve manifolds, IO-Link actuators, and remote I/O blocks on Profinet/EtherNet/IP fieldbus modules. The combination of surge protection and integrated DC-DC keeps the BOM small for IP67 sensor heads where PCB area is constrained and external protection networks are difficult to source.
Designers should budget for the buck regulator's inductor and output capacitors per the datasheet typical application circuit, and verify that the surge protection rating meets the end-application EMC standard (IEC 61000-4-5). The exposed pad requires multiple thermal vias to the inner copper layers for adequate heat extraction at full-load buck operation.

Aplicações típicas
MAX22513ATI+ é adequado para 6 aplicaçãos: 24V Industrial Photoelectric / Proximity Sensor Head, IO-Link Valve Manifold Actuator, IO-Link Remote I/O Block on Profinet/EtherNet/IP Fieldbus, Industrial RFID Reader (IO-Link Interface), Smart Factory Condition Monitoring Sensor, IO-Link Stack Light / Tower Light Indicator.
24V Industrial Photoelectric / Proximity Sensor Head
The MAX22513ATI+ is purpose-built for 24V industrial sensor heads where PCB area is constrained by IP67 housings. Its integrated DC-DC buck regulator derives a 5V or 3.3V rail directly from the 24V bus, eliminating an external switching IC and its inductor area - critical for sensors with <30mm x 30mm PCBs. The +/-1kV/500 ohm integrated surge protection on the C/Q line means no external TVS diode is needed to meet IEC 61000-4-5, saving BOM cost and assembly time. With 1/1 driver IC and half-duplex IO-Link framing across COM1/COM2/COM3, the part handles the standard 24V sensor wake-up pulse and the framed sensor data without any companion PHY IC. For typical 50mA load current on the buck output, thermal rise across the exposed pad is modest (estimated 25 C with 4 thermal vias into a 1oz inner copper pour).
Recomendado
IO-Link Valve Manifold Actuator
IO-Link valve manifolds stack 8-32 solenoid outputs on a single manifold and need a compact transceiver per output or per manifold block. The MAX22513ATI+'s dual LDO outputs and dual driver channels (C/Q plus DO/DI) let a single IC drive one solenoid via C/Q high-current switch and provide a diagnostic return via DO/DI. Integrated surge protection is essential because valve manifolds sit close to motors and relay coils that generate inductive transients on the 24V rail - the MAX22513's +/-1 kV rating absorbs those events without external TVS arrays. Operating temperature -40 C to +125 C covers the inside-of-cabinet thermal envelope of a typical valve manifold. The half-duplex IO-Link protocol is standard IEC 61131-9, ensuring interoperability with all major IO-Link masters (Siemens, Beckhoff, Balluff, Turck, Wago).

IO-Link Remote I/O Block on Profinet/EtherNet/IP Fieldbus
Remote I/O blocks mount beside a Profinet or EtherNet/IP master and aggregate 8-16 digital I/O channels, each exposed as an IO-Link port. The MAX22513ATI+ suits this application because each block typically needs one IO-Link transceiver per port with local 24V-to-logic DC-DC conversion - exactly the MAX22513's integrated feature set. The selectable SPI or pin-strapped host interface lets the block's main microcontroller (often an ARM Cortex-M0) initialize the transceiver without dedicated GPIO overhead. The 8V to 36V input range tolerates industrial 24V rail sag during motor inrush events, and the 550 mV receiver hysteresis prevents false wake-ups from noise on long cable runs. The 28-TQFN-EP-3.5x5.5 mm footprint allows 4 transceiver channels to fit on a 60mm x 40mm block PCB.

Industrial RFID Reader (IO-Link Interface)
IO-Link-connected RFID readers on conveyor lines use the MAX22513ATI+ to bridge between the local RFID frontend ASIC and the IO-Link master. The integrated DC-DC generates the local 5V or 3.3V supply for the RFID frontend from the 24V bus, and the integrated surge protection on C/Q and DO/DI tolerates the ESD events that occur when readers are mounted near moving conveyors with static-generating belts. The dual LDO outputs let one LDO power the RFID frontend while the second powers the host microcontroller, simplifying power-tree design. The MAX22513's low quiescent current in IO-Link sleep mode preserves battery-backed operation where the host MCU uses IO-Link wake-up pulses to power-cycle the reader between scans.

Smart Factory Condition Monitoring Sensor
Vibration, temperature, and acoustic-emission sensors for predictive maintenance typically connect to the factory network via IO-Link. The MAX22513ATI+ integrates the IO-Link physical layer with a local DC-DC converter that powers both the sensor front-end (MEMS accelerometer, RTD, or acoustic transducer) and the host MCU from the 24V bus. The small 28-TQFN-EP package fits inside cylindrical M12 sensor heads where PCB diameter is limited to ~12 mm. The MAX22513's -40 C to +125 C operating range covers harsh factory environments near motors and furnaces. Integrated surge protection eliminates the external TVS that would otherwise need to be hand-soldered onto a small cylindrical sensor PCB.
Recomendado
IO-Link Stack Light / Tower Light Indicator
Multi-color stack lights (red/amber/green/blue) on machine tools use IO-Link to receive status commands from the machine controller. The MAX22513ATI+ drives the C/Q high-current output to switch LED segments via external MOSFETs and provides diagnostic DO/DI for fault feedback. Integrated DC-DC simplifies the power tree because the stack light typically only has a 24V supply wire and no separate logic rail. Surge protection is important on the factory floor where long cable runs pick up motor switching transients. The MAX22513's selectable SPI/pin-strapped interface lets the stack light's low-cost MCU drive the transceiver without firmware overhead for IO-Link configuration.

Notas de projeto
Estimated: at 24V input, 5V/200mA buck output, power dissipation in the buck pass element is approximately (24-5)*0.2 = 3.8 W. The 28-TQFN-EP package with theta_JA around 35 C/W (per typical 4-layer JEDEC board) gives an 130 C junction temperature rise above ambient, requiring derating or reduced buck load above 70 C ambient. Place at least 4 thermal vias (0.3 mm drill, 1 oz copper plating) under the exposed pad connecting to inner copper layers to minimize theta_JA.
Place the buck regulator inductor (LX pin) and the input/output ceramic capacitors within 5 mm of the IC pins to minimize EMI and voltage spikes. Use a 10uF X7R ceramic on V24 to ground, 22uF on the buck output, and 1uF on each LDO output. Keep the C/Q and DO/DI traces away from the LX switch node by at least 3 mm to prevent capacitive coupling of switching noise into the IO-Link signal path.
Do not skip the exposed pad soldering - the exposed pad is the primary heat dissipation path and also the low-impedance ground return for the buck regulator. Use no-clean flux and verify pad solder fillet with X-ray on prototype runs. Verify the SPI/pin-strap mode configuration on power-up by reading the CFG0-CFG2 logic state in firmware, since incorrect mode selection is a common factory-build failure mode for IO-Link sensors.
Route the C/Q and DO/DI traces as differential pairs with 100 ohm characteristic impedance if the IO-Link cable is longer than 5 m, per the IEC 61131-9 physical-layer recommendation. Add a ferrite bead on the V24 supply input to attenuate common-mode noise from the 24V industrial bus. Place the surge protection ground bond directly to chassis ground through a short, wide trace to ensure the +/-1 kV surge rating is preserved in EMC testing per IEC 61000-4-5.
