The NCN5121MNTWG from ON Semiconductor is a receiver-transmitter integrated circuit specifically designed for use in KNX twisted pair networks (KNX TP1-256). This IC facilitates the connection of actuators, sensors, microcontrollers, and other devices within a building network.
Key features include a 9600 baud KNX communication speed, supervision of KNX bus voltage and current, and support for bus current consumption up to 24 mA. It incorporates high-efficiency DC-DC converters providing fixed 3.3 V and selectable 1.2 V to 21 V outputs, along with a linear 20 V regulator. The device offers selectable UART or SPI interfaces to the host controller, with selectable baud rates and optional CRC on UART.
Designed for reliable operation, the NCN5121MNTWG ensures safe coupling and decoupling from the bus, with bus monitoring to warn the host microcontroller of power loss. It operates within an extended temperature range of -40°C to +105°C and is available in a 40-QFN (6x6) surface mount package.
This transceiver IC is suitable for building automation and control applications requiring KNX communication. Its robust design and integrated voltage regulation make it a versatile component for various KNX-based systems.
