MAX22088GTG+

MAX22088GTG+ is a home bus system (HBS) compatible transceiver. This 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. It eliminates the large external AC-blocking inductor typically required in bus-powered applications and improves the signal quality to allow for longer cables. Additionally, this device features an integrated 5V linear regulator to power system loads up to 70mA (max). It supports passing power and data with speeds up to, and exceeding, 200Kbps. This device 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 device to be used in a wide variety of systems. It is used in applications such as HVAC, data over power applications, digital signage, remote monitoring, and sensing.
