Product Summary

The UC1638 family of integrated circuits are advanced pulse width modulators intended for a variety of PWM motor drive and 

amplifier applications requiring either uni-directional or bi-directional drive circuits. Similar in architecture to the UC1637, all 

necessary circuitry is included to generate an analog error signal and modulate two bi-directional pulse train outputs in

 proportion to the error signal magnitude and polarity.
