ECN3061

HIGH-VOLTAGE MONOLITHIC IC ECN3061 ECN3061 is a one-chip three-phase bridge inverter IC which has 6 IGBTs in the circuit. Especially, it is very suitable for controlling the speed of three-phase DC brushless motors which are applied to AC100~110V power supplies. Functions l l Package A Charge pump circuit is integrated. Free wheeling diodes are integrated. Features l l l It can be controlled by PWM with 6 inputs from an external microprocessor. 6 logic inputs are compatible with 5V CMOS and LSTTL outputs. 6 IGBTs can be operated in 20kHz chopping frequency.
