MAX22514ATG+T

Overview

The MAX22514ATG+T is a surge-protected IO-Link transceiver with an integrated DC-DC buck regulator. It operates on a V24 supply voltage ranging from 8V to 36V and supports COM1, COM2, and COM3 data rates. The device includes a high-efficiency 200mA DC-DC buck converter, a 5V linear regulator, and a 3.3V linear regulator. It features configurable C/Q drivers in PNP, NPN, or push-pull modes with selectable slew rates and current limits of 2mA or 5mA. Integrated protection includes ±1kV/500Ω surge tolerance, reverse polarity protection, and hot-plug capability. The component is available in a 24-pin TQFN (4mm x 5mm) package.

Procurement Notes

Verify the specific suffix ATG against official Analog Devices documentation to confirm the exact package type and RoHS compliance status. Ensure that the ordering information matches the required thermal performance and pin configuration for your PCB layout design before finalizing procurement.

Selection Notes

Select this component when designing IO-Link interfaces requiring integrated power management and robust surge protection. The built-in DC-DC regulator reduces external component count. Verify that the logic supply voltage (VL) aligns with your microcontroller's operating range and that the thermal dissipation capabilities of the TQFN package suit your enclosure constraints.

Part Context

The MAX22514 belongs to the Maxim Integrated IO-Link transceiver family, designed specifically for industrial automation environments. It consolidates transceiver functionality, power regulation, and protection into a single compact solution, facilitating smaller form factors for smart sensors and actuators while maintaining compatibility with standard IO-Link protocols.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified alternatives. Generic replacements may lack the integrated surge protection or specific IO-Link timing characteristics required for protocol compliance.
