  • 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

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.
