DRV8426ERGER Frequently Asked Questions (FAQs)

  • The DRV8426ERGER can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • The sense resistor value depends on the desired current sense accuracy and the maximum current rating of your motor. A smaller sense resistor value provides better accuracy but increases power loss. A typical value is 0.1 ohm to 1 ohm.
  • The internal bootstrap diodes are used to generate the gate drive voltage for the high-side FETs. They reduce the need for external components and simplify the design, but they also introduce a voltage drop that affects the overall efficiency and may require additional considerations for high-voltage applications.
  • The DRV8426ERGER has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values determine the overcurrent threshold, and the device will shut down if the current exceeds this threshold.
  • A good PCB layout should minimize the distance between the DRV8426ERGER and the motor, use a solid ground plane, and ensure good thermal conductivity. Thermal management is critical, and a heat sink or thermal pad may be required to keep the device within its operating temperature range.
