DC MOTOR PULSE WIDTH MODULATOR

Description

Features

The SG1731 is a pulse width modulator circuit designed

specifically for DC motor control. It provides a bi-directional pulse

train output in response to the magnitude and polarity of an

analog error signal input. The device is useful as the control

element in motor-driven servo systems for precision positioning

and speed control, as well as in audio modulators and amplifiers

using carrier frequencies to 350 kHz.

. ±3.5 V to ±15 V Control Supply

. ±2.5 V to ±22 V Driver Supply

Dual 100 mA Source/Sink Output Drivers

. 5 kHz to 350 kHz Oscillator Range

. High Slew Rate Error Amplifier

. Adjustable Deadband Operation

Digital SHUTDOWN Input

The circuit contains a triangle waveform oscillator, a wideband

operational amplifier for error voltage generation, a summing/

scaling network for level-shifting the triangle waveform, externally

programmable PWM comparators and dual ±100 mA, ±22 V

totem pole drivers with commutation diodes for full bridge output.

A SHUTDOWN terminal forces the drivers into a floating high-

impedance state when driven LOW. Supply voltage to the control

circuitry and to the output drivers may be from either dual positive

and negative supplies, or single-ended.

High Reliability Features

. Available to MIL-STD-883

. Available to DSCC

– Standard Microcircuit Drawing (SMD)

. MSC-AMS level “S” Processing Available
