Abstract :
A 250-V 1-A three-phase monolithic inverter IC (ECN3010) for variable-speed motor drives has been fabricated. Six insulated-gate bipolar transistors (IGBTs) and fast recovery diodes are integrated on one chip, for the output stages, using dielectric isolation. The IC provides many functions for driving a DC brushless motor by itself. A two-current-level sensing circuit has been developed to limit the motor start-up current and to turn off all the IGBTs when a short-circuit load occurs. The accuracy of the sensing circuit and its temperature dependence are discussed
