Inverter Interface and Digital Deadtime Generator for 3-Phase PWM Controls Type IXDP630 PI IXDP631 PI Package 18-Pin Plastic DIP 18-Pin Plastic DIP Configuration RC Oscillator Crystal Oscillator Temp. Range -40°C to +85°C -40°C to +85°C This 5 V HCMOS integrated circuit is intended primarily for application in three-phase, sinusoidally mutated brushless motor, induction motor, AC servomotor or UPS PWM modulator control systems. It injects the required deadtime to convert a single phase leg PWM mand into the two separate logic signals required to drive the upper and lower semiconductor switches in a PWM inverter. It also provides facilities for output disable and fast overcurrent and fault condition shutdown. In the IXDP630, deadtime programming is achieved by an internal RC oscillator. In the IXDP631, programming is achieved by use of a crystal oscillator. An alternative for both the IXDP630/ 631 is with an external clock signal. Because of its flexibility, the...
