Product details
Overview
MAX22516AWO+ from Analog Devices is an IO-Link data link controller IC integrating a 24V C/Q transceiver, auxiliary digital I/O, integrated 200mA DC-DC buck regulator, and dual linear regulators (5V/3.3V). It autonomously handles IO-Link communication-including process data, ISDU, event, and page handling-without MCU intervention during normal operation, enabling robust sensor node designs in industrial automation.
For engineers reviewing the MAX22516AWO+ datasheet, MAX22516AWO+ pinout, MAX22516AWO+ application, or MAX22516AWO+ equivalent, key selection considerations include COM3 cycle time support (400µs min), integrated ±1kV/500Ω surge protection on all 24V I/O pins, deterministic answer delay, SPI (15MHz) and UART control interfaces, and dual-package availability (WLP 3.53×3.16mm or TQFN-EP 5×5mm).
Technical Context
The MAX22516AWO+ implements a full IO-Link data link layer with dedicated message, ISDU, page, event, mode, and startup handlers-enabling autonomous master request response without host MCU involvement. Its transceiver supports COM1/COM2/COM3 data rates and operates in push-pull, PNP, or NPN modes with programmable slew rate and current limiting.
It integrates three power domains: a high-efficiency 200mA DC-DC buck converter (adjustable output via FB pin, 1.229MHz typical switching frequency), a 5V linear regulator (±1.5% output accuracy, 5mA load capability), and a 3.3V linear regulator (±4.5% load regulation over 1–100mA). All 24V interface pins (V24, C/Q, DO, DI, GNDCQ) feature reverse-voltage, short-circuit, and ±1kV/500Ω surge protection per IEC 61000-4-5.

Equivalent & Alternatives
The following parts are listed as comparable options for similar IO-Link data link controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX22515AWO+ | Omits integrated DC-DC and 3.3V regulator; retains 5V LDO, C/Q transceiver, and data link layer. | Requires external 3.3V supply and DC-DC; suitable when system already provides 3.3V/6V rails. | Select MAX22515AWO+ only if board space allows external regulators and cost sensitivity outweighs integration benefit. |
| TI DP83822IRGZT | PHY-only Ethernet PHY (10/100BASE-T1), no IO-Link stack, no DC-DC, no 24V I/O protection. | Designed for TSN-capable industrial Ethernet nodes-not compatible with IO-Link infrastructure. | Not a functional alternative; only relevant for Ethernet-based sensor architectures replacing IO-Link entirely. |
Compared with MAX22516AWO+, the MAX22515AWO+ reduces integration but maintains identical IO-Link timing, protection, and SPI/UART interfaces-making it viable where external power is available. The TI DP83822IRGZT belongs to a different protocol stack and cannot substitute in IO-Link systems.

FAQ
What is the maximum supported IO-Link communication speed for the MAX22516AWO+?
The MAX22516AWO+ supports all three IO-Link communication speeds: COM1 (4.8 kbps), COM2 (38.4 kbps), and COM3 (230.4 kbps). Its hardware-accelerated data link layer guarantees deterministic answer delay and supports minimum 400µs cycle time at COM3-critical for high-throughput sensor networks.
Does the MAX22516AWO+ require an external crystal or oscillator?
No, the MAX22516AWO+ does not require an external crystal. It derives timing from its internal oscillator and supports optional external clock input via the MCLK pin (configurable from 1.78MHz to 31MHz using ClkDiv[2:0]). The internal clock meets IO-Link jitter requirements without external components.
Can the MAX22516AWO+ operate without the integrated DC-DC converter enabled?
Yes, the MAX22516AWO+ can operate with the DC-DC disabled. In that case, external 5V and 3.3V supplies must be provided to V5 and V33 respectively, and LIN must be tied to V5 to disable the 5V LDO. The device retains full IO-Link functionality, C/Q transceiver operation, and protection features.
How is surge protection implemented on the C/Q pin of the MAX22516AWO+?
The MAX22516AWO+ integrates ±1kV/500Ω surge protection on the C/Q pin per IEC 61000-4-5 Ed. 3, achieved through internal clamping circuitry and robust ESD structures. This eliminates the need for external TVS diodes while maintaining signal integrity and meeting industrial immunity standards without layout compromises.
What package options are available for the MAX22516AWO+ and how do they differ thermally?
The MAX22516AWO+ is offered in two packages: 40-pin TQFN-EP (5mm × 5mm) and 42-bump WLP (3.53mm × 3.16mm). On a 4-layer PCB, the TQFN achieves θJA = 28°C/W and θJC = 2°C/W, while the WLP achieves θJA = 36.38°C/W. Both are rated for −40°C to +125°C operation and support reflow per JEDEC J-STD-020.
