NCN5110
Transceiver for KNX
Twisted Pair Networks
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
