NCN5110

Transceiver for KNX Twisted Pair Networks NCN5110 Introduction NCN5110 is a receiver−transmitter IC suitable for use in KNX twisted pair networks (KNX TP1−256). It supports the connection of 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 voltages for its own power needs as well as to power external devices, for example, a microcontroller. 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. Key Features Supervision of KNX Bus Voltage and Current Supports Bus Current Consumption up to 40 mA High Efficient DC−DC Converters ♦ 3.3 V Fixed ♦ 1.2 V to 21 V Selectable Control and Monitoring of Power Regulators Linear 20 V Regulator Direct Coupling of Analog Signaling to Host No Crystal Required Optional Clock of 8 or 16 MHz for External Devices Temperature Monitoring Extended Operating Temperature Range −40°C to +105°C These Devices are Pb−Free and are RoHS Compliant DATA SHEET www.onsemi.com 1 40 QFN40 MN SUFFIX CASE 485AU MARKING DIAGRAM NCN5110 AWLYYWWG A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 23 of this dat...
