NCN5110 Transceiver for KNX Twisted Pair Networks Introduction NCN5110 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. NCN5110 handles the transmission and reception of active pulses on the bus. It generates from the unregulated bus voltage stabilized QFN40 voltages for its own power needs as well as to power external devices, MN SUFFIX CASE 485AU for example, a microcontroller. 1 40 NCN5110 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.
