DRV421RTJT Frequently Asked Questions (FAQs)

  • The DRV421RTJT can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • The DRV421RTJT requires a single 5V supply (VCC) and a separate 3.3V or 5V supply (VDD) for the internal logic. Ensure both supplies are properly decoupled and filtered.
  • Keep the high-current paths (VIN, VOUT, and GND) short and wide, and use a solid ground plane to minimize inductance and noise. Avoid routing sensitive signals near the high-current paths.
  • The DRV421RTJT is designed for 3-phase brushless DC motors. For other motor types, consult the datasheet and application notes for specific configuration and programming requirements.
  • The nFAULT pin is an active-low fault indicator. It goes low when the device detects an overcurrent, overtemperature, or undervoltage condition. Use it to trigger a system reset or shutdown in fault conditions.
