HVAC (Air conditioning)

Heating, Ventilation and Air Conditioning (HVAC) systems have become increasingly commonplace. However there has been a clear drive towards greater efficiency to meet the demand for more sustainable and eco-friendly units. Improving overall system efficiency and thermal performance is fundamental to this change through variable speed compressors or inverter technology. In addition, smart HVAC systems are increasingly interconnected and draw data from both internal and external sensors including external temperature, humidity, brightness, and even the position of the sun.

Design considerations

  • Nexperia’s clip-bond package options enable high-efficiency on motor control (better duty precision) and higher frequency DC:DC conversion
  • Best thermal performance thanks to clip-bond package and lower switch losses. Allows use of air cooled heat spreader rather than more expensive and complex water cooled systems
  • Best in class SOA and avalanche capabilities increase robustness and reliability of the system (Higher ID current allowed in PWM mode)
  • As a worldwide leading producer of ESD components, HMI and Display protection secured from any ESD damage
  • Battery booster enables extension of cell battery lifetime by up to 3 times

H-bridge motor controller design using Nexperia discrete semiconductors and logic ICs

The H-bridge circuit is a full bridge DC-to-DC converter allowing operation of a brushed DC motor (48 V max, 12 V min, 5 A max). The key feature of this design is that all electronic functions are designed with Nexperia discrete and logic IC components (low cost, no micro-controller or software needed).
