HIGH-VOLTAGE MONOLITHIC IC ECN3021
●ECN3021 is a single chip three-phase bridge inverter IC which has 6 IGBTs in the circuit. Especially, it is very suitable for controlling the speed of 3-phase DC brushless motors to which converted AC200~230V power supplies are applied. Fig. 1 shows the internal block diagram.
●Functions
■Integrated charge pump circuit
■Integrated free wheel diodes
■Integrated PWM circuit
■Integrated FG circuit
■Integrated over current protection circuit
■Integrated rotating direction monitor circuit
●Features
■Speed control for a 3-phase DC brushless motor is available with an external microprocessor.
■Bottom arm circuits can be operated in 20kHz chopping frequency of PWM.
