ON Semiconductor 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.
The NCN5150 achieves Universal Asynchronous Receiver/Transmitter (UART) communication speeds of up to 38400 baud and includes a programmable power level of up to two (SOIC-packaged version) or six (QFN-packaged version) unit loads which are available for use in external circuits through an integrated 3.3 volt (V) low drop-out (LDO) regulator. Low internal power consumption makes extra power available for the sensor in the application, while low voltage bus operation (down to 9.2 V) allows operation on extended M-BUS networks.
The NCN5150 is available in a choice of SOIC-16 and QFN-20 packages; the SOIC-16 offers pin-to-pin compatibility with existing devices currently on the market, plus a number of performance improvements. The dimensions of the QFN package make it ideal for use in the growing number of space constrained applications.
