DRV120APWR datasheet by Texas Instruments

DRV120APWR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the DRV120APWR?
  The DRV120APWR can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure the DRV120APWR is properly powered?
  The DRV120APWR requires a 5V power supply (VCC) and a 3.3V or 5V logic supply (VDD). Ensure that the power supplies are stable and decoupled with capacitors to prevent noise and oscillations.
• What is the recommended PCB layout for the DRV120APWR?
  Use a 4-layer PCB with a solid ground plane, and place the DRV120APWR near the motor to minimize noise and EMI. Keep the high-current paths short and wide, and use thermal vias to dissipate heat.
• How do I configure the DRV120APWR for different motor types?
  The DRV120APWR can be configured for different motor types (e.g., stepper, DC, or brushless) by adjusting the input pins (IN1, IN2, and EN) and the internal registers. Refer to the datasheet and application notes for specific configuration details.
• What are the key considerations for EMI and noise reduction with the DRV120APWR?
  Use a shielded cable for the motor connections, add a common-mode choke, and ensure good PCB layout practices (e.g., keep high-current paths short, use a solid ground plane, and decouple power supplies).
