IXDP631PI

This 5 V HCMOS integrated circuit IXDP631PI is intended primarily for application in three-phase, sinusoidally commutated brushless motor, induction motor, AC servomotor or UPS PWM modulator control systems. The IXDP631PI injects the required deadtime to convert a single phase leg PWM command into the two separate logic signals required to drive the upper and lower semiconductor switches in a PWM inverter. The IXDP631PI also provides facilities for output disable and fast overcurrent and fault condition shutdown.

In the IXDP631PI, deadtime programming is achieved by an internal RC oscillator. In the IXDP631PI, programming is achieved by use of a crystal oscillator. An alternative for both the IXDP631PI is with an external clock signal. Because of its flexibility, the IXDP631PI is easily utilized in a variety of brushed DC, trapezoidally commutated brushless DC, hybrid and variable reluctance step and other more exotic PWM motor drive power and control circuit designs.
