Inverter Interface and Digital Deadtime Generator

for 3-Phase PWM Controls

Features

Type

Package

Configuration

Temp. Range

5 V HCMOS logic implementation

maintains low power at high speed

IXDP630 PI

IXDP631 PI

18-Pin Plastic DIP

RC Oscillator

-40°C to +85°C

Schmitt trigger inputs and CMOS

logic levels improve noise immunity

Crystal Oscillator

Simultaneously injects equal dead-

time in up to three output phases

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.

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.

Replaces 10-12 standard SSI/MSI

logic devices

Allows a wide range of PWM

modulation strategies

Directly drives high speed

optocouplers
