MAX22288ATG+T

Overview

The MAX22288ATG+T is a Home Bus System (HBS) compatible transceiver designed for applications where data and power are transmitted over a single pair of wires. It supports data rates up to 200kbps and operates within a supply voltage range of 4.5V to 5.5V, with a typical current consumption of 18mA at 57.6kbps. The device features dynamic cable termination, adjustable receiver thresholds, and configurable transmit slew rates to optimize signal quality. It provides integrated protection against IEC 61000-4-2 ESD (±8kV contact, ±15kV air-gap) and IEC 61000-4-5 surge events. The component is specified for operation from -40°C to +125°C and is housed in a compact 4mm x 4mm TQFN package.

Feature Summary

• Dynamic cable termination improves signal integrity for high-speed applications over longer cables
• Configurable receiver thresholds and driver slew rates allow adaptation to diverse system requirements
• Integrated protection ensures robust communication in harsh industrial environments
• Pin-to-pin compatible with the MAX22088 HBS Compatible Transceiver

Applications

• HVAC systems
• Building controllers
• Industrial IoT networks

Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging when sourcing components. Confirm that the 'A' designation corresponds to the extended temperature range of -40°C to +125°C. Ensure compatibility with existing HBS infrastructure designs referencing the MAX22088. Check for RoHS compliance status indicated by the '+' suffix in official documentation.

Selection Notes

Select this transceiver for HBS applications requiring an external power supply rather than bus-powered operation. Consider the MAX22088 if active inductor functionality is needed for bus-powered nodes. Evaluate the need for dynamic termination based on cable length and data rate requirements. Verify that the 4mm x 4mm TQFN package fits the available PCB footprint constraints.

Part Context

The MAX22288 belongs to the Home Bus System (HBS) transceiver family developed by Analog Devices/Maxim Integrated. It serves as a direct pin-compatible alternative to the MAX22088, offering similar interface capabilities without the active inductor feature. This positioning allows designers to choose between bus-powered and externally powered HBS node implementations based on system architecture needs.

Replacement Considerations

The MAX22288ATG+ is the tube-packaged equivalent of the MAX22288ATG+T. Both share identical electrical characteristics and pinouts. No other functional substitutes are documented in the provided datasheet.
