BridgeSwitch™ feature high- and low-side FREDFETs (Fast Recovery Diode Field Effect Transistors) with integrated lossless current sensing, resulting in inverter conversion efficiency of up to 98.5% in brushless DC (BLDC) motor drive applications to 300 W. Superior efficiency along with the distributed thermal footprint eliminates the need for a heatsink, reducing both system cost and weight. Integrated lossless current sensing, bus voltage sensing and system-level thermal sensing makes this device family ideal for BLDC motors.

 

Key features

  • Heat-sink less design up to 300W
  • Self supplied, no need of external Psu
  • 600V FREDFETs with integrated lossless current sensing, allows up to 98.5%
  • Simplifies system level safety certification, Class A rated control software possible

 

Additional features

  • 600V Integrated FREDFETs (Fast Recovery Diode Field Effect Transistors) allows up to 98.5% inverter efficiency and low EMI
  • No heat-sink required up to 300W
  • Fully self-supplied simplifies system auxiliary power supply
  • Low and high-side cycle-by-cycle current limit simplifies system level certification
