IRS4426SPBF Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the IRS4426SPBF is 500 kHz, but it can be used up to 1 MHz with reduced performance.
  • To ensure the bootstrap capacitor is properly charged, make sure the high-side driver is enabled before the low-side driver, and the bootstrap capacitor should be at least 10 times the gate charge of the high-side MOSFET.
  • The recommended dead time between high-side and low-side switching is typically around 100-200 ns to prevent shoot-through current and ensure reliable operation.
  • Yes, the IRS4426SPBF can be used with a different voltage supply, but the recommended operating range is 10V to 15V. Operating outside this range may affect performance and reliability.
  • To protect the IRS4426SPBF from overvoltage and undervoltage conditions, use a voltage regulator or a voltage supervisor to ensure the supply voltage remains within the recommended operating range.
