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 pro
portion to the error signal magnitude and polarity.
**FEATURES**
• Single or Dual Supply Operation
• Accurate High Speed Oscillator
• Differential X5 Current Sense Amplifier
• Bidirectional Pulse-by-Pulse Current Limiting
• Programmable Oscillator Amplitude and PWM Deadband
