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.
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
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.
