ON Semiconductor (Phoenix, AZ) has introduced a new integrated slave transceiver for use in two-wire Meter Bus (M-BUS) slave devices and repeaters. The NCN5150 provides all necessary functionality to satisfy the EN 13757-2 and EN 1434-3 standards that describe the physical layer requirements for remote meter reading M-BUS applications in multi-energy, heating and cooling, water, and gas meters. Features include:

  • Universal Asynchronous Receiver/Transmitter (UART) communication speeds of up to 38400 baud.
  • A programmable power level of up to 2 (SOIC-packaged version) or 6 (QFN-packaged version) unit loads.
  • A robust build.
  • A wide operating temperature range from -40° to +85°C.
  • Power fail function.
  • Fast start-up.
  • Ability to support the powering of a slave device from either the bus or an external power supply.
