MAX22088GTG+

Overview

The MAX22088GTG+ is a Home Bus System (HBS) compatible transceiver in a 24-pin, 4mm x 4mm TQFN package. It supports data rates from 9600bps to 200kbps over a single pair of wires carrying both power and data. The device features an integrated active inductor to eliminate external AC-blocking inductors and includes a 5V linear regulator capable of supplying up to 70mA. Operating voltage ranges from 4.6V to 24V at VRAW, with an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrated active inductor eliminates the need for bulky external AC-blocking inductors in bus-powered applications.
• Dynamic cable termination improves signal quality for high-speed communication over longer cables.
• Configurable receiver thresholds, hysteresis, and transmit slew rate allow flexible design optimization.
• Built-in IEC 61000-4-2 ESD protection ensures robust operation in harsh industrial environments.

Applications

• HVAC systems
• Data over Power applications
• Digital signage networks
• Remote monitoring and sensing

Procurement Notes

Verify the specific suffix GTG+ corresponds to the lead-free RoHS-compliant tube packaging variant. Confirm that the required operating environment falls within the specified -40°C to +105°C temperature range. Ensure system power requirements do not exceed the internal LDO's 70mA limit or utilize external regulation if higher current is needed.

Selection Notes

Select this component when designing HBS nodes that require power consumption from the bus without external blocking inductors. Compare against the MAX22288 if the application only requires data transmission without power sourcing capabilities. Consider the compact 4mm x 4mm footprint for space-constrained PCB layouts.

Part Context

This part belongs to the MAX22088 family of Home Bus System transceivers manufactured by Analog Devices / Maxim Integrated. It is specifically designed for simplified home bus architectures where data and power share a single twisted pair. The device integrates functions typically requiring multiple discrete components into a single compact IC.

Replacement Considerations

The MAX22288 serves as a pin-compatible alternative for applications that do not require the integrated active inductor or power sourcing capabilities. Verify functional compatibility regarding the absence of the active inductor circuitry before substitution.
