SG1731/SG2731/SG3731  
DC MOTOR PULSE WIDTH MODULATOR  
FEATURES  
DESCRIPTION  
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.  
• ±3.5V to ±15V control supply  
• ±2.5V to ±22V driver supply  
Dual 100mA source/sink output  
drivers  
5KHz to 350KHz 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 ±100mA,  
±22V totem pole drivers with commutation diodes for full bridge output.  
A
HIGH RELIABILITY FEATURES  
- SG1731  
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.  
Available to MIL-STD-883  
LMI level “S” processing available
