NCN5130 Transceiver for KNX Twisted Pair Networks Introduction NCN5130 is a receivertransmitter IC suitable for use in KNX twisted pair networks (KNX TP1256). It supports the connection of www.onsemi.com actuators, sensors, microcontrollers, switches or other applications in a building network. NCN5130 handles the transmission and reception of data on the bus. It generates from the unregulated bus voltage stabilized voltages for its QFN40 own power needs as well as to power external devices, for example, a MN SUFFIX CASE 485AU microcontroller. 1 40 NCN5130 assures safe coupling to and decoupling from the bus. Bus monitoring warns the external microcontroller in case of loss of power so that critical data can be stored in time.
