12–48 V power tools and cordless equipment

When heavy duty lithium battery packs and brushless DC motors were first combined, no one would have guessed the impact they would have on cordless power tools let alone drones, vacuum cleaners and gardening equipment. Yet today cordless devices continue to replacing a whole range of mains-powered consumer and industrial equipment. While 12-24 V systems are still common, more and more manufacturers are switching to more powerful 36 V or 48 V systems. Of course with more power comes the need for greater safety and Nexperia’s portfolio helps provide that safety without sacrificing efficiency.

Design considerations

  • Trend is towards more powerful PWM driven Brushless DC motor control 
  • Best thermal performance thanks to clip-bonding package, Rth 3x better than competition resulting in half the temperature
  • Lower switch losses further improve thermal behaviour
  • Reliable clip-bonding package technology for high anti stall robustness
  • As a worldwide leading producer of ESD components, HMI and Displays will be secured from any ESD damage
  • LFPAK and CFP (both clip-bond package) allow high-efficiency motor drive and DCDC converter solutions while reducing costs (less heating to dissipate, smaller inductance and capacitor)
  • For specific applications MOSFETs may need to meet different spacing requirements like UL2595

MOSFET and GaN FET Handbook

Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
