A Smart building is built on a secure, scalable connectivity fabric linking sensors, actuators, power electronics, and IoT edge devices into one coordinated ecosystem. These devices communicate locally and through the cloud to enable automation, remote diagnostics, and real‑time optimization of functions such as lighting, HVAC, access control, and appliances. Homeowners or facility managers can remotely adjust temperature, monitor security, manage energy usage, or control connected loads via a phone, tablet, or PC.
Modern smart buildings also integrate Small Electric Vehicles (SEVs) e‑bikes, e‑scooters, delivery robots, and micro‑mobility platforms which depend on intelligent battery management, efficient power conversion, and safe charging. Smart charging docks use load balancing and energy‑aware scheduling to reduce peak demand and maximize renewable or low‑tariff energy. onsemi supports this with high‑efficiency MOSFETs, SiC/GaN power devices, current‑sense amplifiers, and battery‑management ICs that improve charger compactness, safety, and runtime.
Battery‑powered tools in garages or maintenance areas also benefit from IoT connectivity. Smart chargers can report state of charge (SoC), state of health (SoH), cycle count, and predictive maintenance data. onsemi’s DC‑DC converters, power stages, and protection ICs enhance charging efficiency, thermal performance, and battery safety.
A key component of smart‑building energy systems is the heat pump, which transfers heat using an inverter‑driven compressor. Connected to the building’s IoT network, heat pumps can optimize energy consumption using AI algorithms, occupancy data, and weather forecasts. From a semiconductor perspective, they rely on SiC MOSFETs, gate drivers, PFC controllers, and current/temperature sensors enabling variable‑speed operation, high COP, and reduced total energy use.
