SG1731/SG2731/SG3731  
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
