Power Integrations BridgeSwitch Motor Drivers

Driving single and three-phase brushless DC motors up to 400 W and 98% efficiency without heatsinks, BridgeSwitch ICs integrate two high-voltage N-channel power FREDFETs with low and high-side self-supplied drivers in a small-outline package - eliminating external auxiliary power supplies. The MCU-agnostic devices support sinusoidal, trapezoidal, and sensorless field-oriented control implementations. BridgeSwitch hardware-based system protection enhances safety, reliability and accelerates time-to-market.
