- Heat-sink less design up to 400 W
- Self supplied, no need of external PSU
- 600 V FREDFETs with integrated lossless current sensing
- Simplifies system level safety certification, Class A rated control software possible
The BridgeSwitch™ family of integrated half-bridges feature high- and low-side FREDFETs (Fast Recovery Diode Field Effect Transistors) with integrated lossless current sensing, resulting in the inverter conversion efficiency of up to 99.2% in brushless DC (BLDC) motor drive applications up to 400 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 make this device family ideal for BLDC motors.
