"One Shot"
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 IXDP630/
631 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.
This 5 V HCMOS integrated circuit is
intended primarily for application in
three-phase, sinusoidally commutated
brushless motor, induction motor, AC
servomotor or UPS PWM modulator
control systems. It 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. It also provides facilities
for output disable and fast overcurrent
and fault condition shutdown.
