Motor Controls

Power Integrations offers a broad range of highly integrated, high-voltage ICs for auxiliary power supplies for motor control and small DC motor drives. Each IC includes a ≥700 V power MOSFET combined with control and protection circuitry on a single chip. Features include current limiting and thermal shutdown with automatic fault recovery capability to improve reliability, frequency jittering to reduce EMI, and EcoSmart™ technology to dramatically reduce standby energy waste.
