Able to dramatically simplify the creation of high-voltage, inverter-driven, one- or three-phase PM or BLDC motor drives, the BridgeSwitch-2 family of half-bridges from Power Integrations combine two high-voltage, N-channel power FREDFETs with low- and high-side drivers in a single small-outline package.

A reference design for a 150-W, high-efficiency, three-phase inverter using three BridgeSwitch-2 BRD2463C devices to drive a high-voltage BLDC motor is shown in the video, showcasing BridgeSwitch-2 device performance.
