NCN5151
Wired M-BUS Slave Transceiver with Low Power Mode Support
Description The NCN5151 is a single−chip integrated slave transceiver for use
in two−wire Meter Bus (M−BUS) slave devices and repeaters. The NCN5151 reuses the NCN5150 features and adds two low
power modes: a 2−wire low power mode dedicated to System for meter Communication and Readout for powerless meters (SCR) and a 3−wire low power mode allowing support for wireless applications. When configured in low power mode, the transceiver will not behave anymore as a constant current source in order to save energy.
When configured and used in M−BUS mode, the NCN5151 transceiver provides all of the functions needed to satisfy the European Standards EN 13757−2 and EN 1434−3 describing the physical layer requirements for M−BUS.
