# ✅ Common Features of DC Motor Driver Chips

These are essential or desirable features for a DC motor driver IC, especially for brushed DC motors (like 130/230 motors):

🔁 1. Bidirectional Drive

  • Allows motor to rotate clockwise (CW) and counter-clockwise (CCW)
  • Requires an H-bridge circuit internally

🎚️ 2. PWM (Pulse Width Modulation) Support

  • Enables speed control by adjusting duty cycle
  • Most drivers support PWM input on EN or IN pins

🧠 3. Input Logic Compatibility

  • Accepts standard 3.3V or 5V logic signals from microcontrollers (Arduino, Raspberry Pi, ESP32, etc.)

🔐 4. Built-in Protection Features

  • Overcurrent protection: Prevents damage from short circuits or heavy loads
  • Thermal shutdown: Protects the IC from overheating
  • Undervoltage lockout: Disables the chip if supply voltage drops too low

📈 5. Current Rating

  • Should handle the motor's stall current without damage (e.g., 1A+ for 230 motor)

🧲 6. Brake Mode (Optional)

  • Allows fast motor stop by shorting terminals
  • Useful for precise or quick motion control

🔄 7. Sleep or Enable Pin

  • Allows putting the driver in low-power mode or turning off the motor without cutting power

🔌 8. Separate Motor and Logic Supply

  • Often supports dual power rails (e.g., 5V logic and 6–12V motor power)

⚡ 9. Flyback Diodes (Freewheeling Diodes)

  • Either built-in or required externally
  • Protects the driver from voltage spikes caused by motor inductance

🧩 10. Compact Footprint / Module Availability

  • Available as SMD ICs or in breakout boards for prototyping

📘 Bonus Features (Advanced Chips)

  • Current sensing output (e.g., DRV8871)
  • I2C/SPI control (e.g., DRV8830 has I2C)
  • Phase/Enable or IN1/IN2 logic modes
  • Soft start / controlled acceleration
