ON Semi’s newest integrated slave transceiver

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. Designed using ON Semiconductor’s latest mixed-signal technology, the NCN5150 is robust and has a wide operating temperature range of -40 °C to +85 °C, making it suitable for use in the varied and often unpredictable operating environments typical in this market sector. Other key features of the polarity independent devices include a power fail function, fast start-up, and the ability to support the powering of a slave device from either the bus or an external power supply. “Remote meter reading is a rapid growth market in both domestic and industrial sectors said,” said Ryan Cameron, vice president of Industrial and Timing products at ON Semiconductor. “The NCN5150 integrated slave harnesses ON Semiconductor’s advanced mixed-signal technology know-how to provide the required performance levels for these applications, not only in terms of standards compliance, but also ruggedness, efficiency, speed and flexibility.” Packaging and Pricing The RoHS-compliant NCN5150 is priced at $1.30 USD for the SOIC-16 version in 3,000 unit quantities, and at $1.26 USD for the QFN-20 version in 2,500 unit quantities.
