Description

The MAX22088 Home Bus transceiver complies with the Home Bus standard, where data and power are passed on one single pair of wires, while minimizing the need for external components. The MAX22088 eliminates the large external AC-blocking inductor typically required in bus powered applications and improves the signal quality to allow for longer cables. Additionally, the MAX22088 features an integrated 5V linear regulator to power system loads up to 70mA (max).

The MAX22088 supports passing power and data with speed up to, and exceeding, 200kbps. The MAX22088 features dynamic cable termination to improve the signal quality for applications with high data rates.

Additional features include adjustable receiver hysteresis, receiver thresholds and driver slew rate allow the MAX22088 to be used in a wide variety of systems.

Integrated protection (IEC 61000-4-2 ±8kV Contact and ±15kV Air-Gap ESD) ensures robust communication in harsh industrial environments. The MAX22088 is specified for operation over the -40°C to +105°C temperature range and is available in a compact 24-pin 4mm x 4mm TQFN package.
