A3967SLBTR-T Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the A3967SLBTR-T is -20°C to 85°C.
  • Ensure a stable power supply voltage between 4.5V and 5.5V, and decouple the power pins with a 10uF capacitor to minimize noise and voltage drops.
  • Use a 4-layer PCB with a solid ground plane, and keep the motor driver traces short and wide to minimize inductance and noise. Keep the sense resistors close to the IC.
  • Check the power supply voltage, ensure proper PCB layout, and verify the input signals. Use an oscilloscope to check the output waveforms and verify the motor is properly connected.
  • No, the A3967SLBTR-T is designed for stepper motors only. For brushless DC motor control, consider using a dedicated BLDC motor driver IC.
