IR21844PBF Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the IR21844PBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
  • To ensure the bootstrap capacitor is properly charged, make sure to follow the recommended bootstrap capacitor value and charging resistor value, and ensure the high-side driver is enabled before the low-side driver.
  • The recommended deadtime between the high-side and low-side drivers is typically around 100-200 ns, but this can vary depending on the specific application and requirements.
  • To protect the IR21844PBF from overvoltage and undervoltage conditions, use a voltage regulator or a voltage supervisor to ensure the supply voltage is within the recommended range, and consider adding overvoltage protection (OVP) and undervoltage protection (UVP) circuits.
  • The maximum allowable voltage on the VCC pin is 20 V, but it's recommended to keep it below 15 V for reliable operation.
