UC2638DWTRG4

先进的PWM电机控制器 Advanced PWM Motor Controller

**DESCRIPON**

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

• Dual 500mA Totem Pole Output Drivers

• Dual 60V, 50mA Open Collector Drivers

• Undervoltage Lockout
