Infineon’s semiconductor solutions for the Smart Building of tomorrow

Design truly energy efficient and secure smart buildings with Infineon’s semiconductor portfolio

Buildings are today on the edge to become truly smart - due to advancements in digitalization and modern infrastructure. Smart buildings collect data from a multitude of connected IoT devices, process them independently and adjust the building’s operations accordingly in an autonomous way. All thanks to an array of semiconductors embedded in smart building applications which enable buildings to sense – compute – actuate in a secured environment. Let’s have a look at how Infineon semiconductor products make buildings power efficient, cost-cutting and intuitive.

The smart building experience already starts at the entrance of the building when entering it without any physical keys by simply using either a smart card or NFC features of a connected device with Infineon’s CIPURSE™ solutions.

Once inside the smart building, Infineon’s XENSIV™ sensor portfolio allows smart buildings to sense its environment and act accordingly – without you even noticing it. Infineon’s 24 GHz radar captures presence of people with micro motion detection as well as information about speed of objects and direction of movement. This information is crucial to adjust lighting and other smart building operations according to room occupancy, thus saving energy without you having to remember to turn off these devices.

While sensors enable lighting systems to only be switched on and off when truly needed, Infineon’s highly efficient LED drivers and XDP™ digital power controllers make smart lighting systems more power efficient and comfortable – allowing building operators to save both energy and costs in a smart way.

However, smart buildings do not stop at detecting people’s presence. They also continuously monitor their operation’s state and send this information to the building management system. Elevators in smart buildings know exactly their current floor and altitude level as well as their usage profile to optimize their operation and maintenance patterns making sure that you don’t have to wait for them longer than needed. How do they do that? By relying on data collected by Infineon’s highly precise barometric pressure sensors family.

The same sensors can be used in smart HVAC systems to continuously monitor the airflow and provide maintenance information. Before a filter is blocked shutting down the air conditioning system, an alert can be automatically sent to the building management system and maintenance can be triggered. Similarly, Infineon’s MEMS microphones or 3D magnetic sensors can be included in drives which enable predictive maintenance and condition monitoring on top.

CIPOS™ IPM family and iMOTION™ controllers enables you to quickly design motor drive applications for smart and connected equipment with fans, pumps to general purpose drives. In combination with double hall sensors, applications like smart window shutters precisely know their speed, direction as well as state and can report this to the building management system to regulate the sunlight for the tenants’ comfort.

To make sure that smart buildings are not only intelligent, but also secure, Infineon’s OPTIGA™ family of security solutions provides hardware security along the entire data value chain to increase your data’s protection level. It enables hardware security from the edge devices, over gateways, up to central building management systems in the building itself or up to the Cloud securing the sense – compute – actuate flow by hardware security.

Discover now how Infineon’s highly efficient and reliable products enable low-power, cost-saving and intuitive smart buildings.

XDP™ Digital Power and LED Driver: XDPL8218 + BCR601

The XDPL8218 integrates a constant voltage quasi-resonant digital flyback XDP™ controller with algorithms for high power factor and low THD. Main application field for XDPL8218 digital control IC for LED drivers are dual stage designs with a DC-DC stage at secondary side and XDPL8218 as primary side. The control IC manages wide load ranges and reacts fast and stable to dynamic load changes. The digital core of the XDPL8218 control IC enables high efficiency over wide output power range. A comprehensive parameter set allows the adaptation of the circuit to a wide set of LED driver features, e.g. the BCR601.

BCR601 is a linear LED controller IC regulating the LED current with an external driver transistor. It supports either NPN bipolar transistors or N-channel MOSFETs to cover a wide LED current and power range up to several amperes. The LED current is fully scalable by dimensioning an external resistor at MFIO pin.

A unique feature of BCR601 is to provide feedback to the primary side via an optocoupler to control the output voltage of the primary side converter, e.g. XDPL8218. The integrated control loop minimizes the voltage overhead and power dissipation of the external driver transistor. This capability, coupled with the adjustment of voltage overhead by external configuration according to application needs, leads to efficient LED systems.

AC line ripple suppression, analog dimming option and various protection features round up this device for LED drivers allowing for flicker-free light and longevity of LEDs.
