IR21814SPBF datasheet by International Rectifier

IR21814SPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR21814SPBF?
  The maximum operating frequency of the IR21814SPBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
• How do I ensure proper thermal management of the IR21814SPBF?
  Proper thermal management can be achieved by providing a heat sink with a thermal resistance of less than 10°C/W, and ensuring good airflow around the device. The maximum junction temperature is 150°C.
• What is the recommended dead time for the IR21814SPBF?
  The recommended dead time for the IR21814SPBF is 100-200 ns, but it can be adjusted based on the specific application requirements.
• Can I use the IR21814SPBF with a bootstrap capacitor?
  Yes, the IR21814SPBF can be used with a bootstrap capacitor to generate the high-side gate drive voltage. The recommended bootstrap capacitor value is 10-22 nF.
• How do I protect the IR21814SPBF from overvoltage and undervoltage conditions?
  The IR21814SPBF has built-in overvoltage protection (OVP) and undervoltage protection (UVP) features. Additionally, external protection circuits can be used to provide extra protection against voltage transients and spikes.
