IR4426PBF Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the IR4426PBF is 500 kHz, but it can be operated at higher frequencies 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 the high-side and low-side drivers is typically around 100-200 ns to prevent shoot-through current.
  • To protect the IR4426PBF from overvoltage and undervoltage conditions, use a voltage regulator or a voltage supervisor to ensure the supply voltage is within the recommended range of 10-20V.
  • The maximum allowable power dissipation of the IR4426PBF is dependent on the ambient temperature and the thermal resistance of the package. Refer to the thermal derating curve in the datasheet to determine the maximum allowable power dissipation.
