IRS21851SPBF datasheet by International Rectifier

IRS21851SPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IRS21851SPBF?
  The maximum operating frequency of the IRS21851SPBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
• How do I ensure the bootstrap capacitor is properly charged?
  To ensure the bootstrap capacitor is properly charged, make sure the VCC pin is powered up before the input signal is applied, and the bootstrap capacitor value is chosen according to the datasheet recommendations.
• What is the recommended dead time for the IRS21851SPBF?
  The recommended dead time for the IRS21851SPBF is typically between 100 ns to 500 ns, depending on the specific application and switching frequency.
• Can I use the IRS21851SPBF with a different voltage supply?
  The IRS21851SPBF is designed to operate with a 12 V to 15 V supply voltage, but it can be used with a different voltage supply with proper design considerations and component selection.
• How do I protect the IRS21851SPBF from overvoltage and undervoltage conditions?
  To protect the IRS21851SPBF from overvoltage and undervoltage conditions, use voltage regulators, TVS diodes, and/or zener diodes to clamp the voltage within the recommended operating range.
