IR2101PBF datasheet by International Rectifier

IR2101PBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR2101PBF?
  The maximum operating frequency of the IR2101PBF 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 high-side driver output is not loaded during the bootstrap capacitor charging period, and the bootstrap capacitor value is chosen according to the application's requirements.
• What is the purpose of the SD pin, and how do I use it?
  The SD (Shutdown) pin is used to disable the device and reduce the quiescent current. To use it, connect the SD pin to a logic-level signal that goes low to shut down the device and high to enable it.
• How do I choose the right value for the bootstrap capacitor?
  The bootstrap capacitor value depends on the application's requirements, such as the switching frequency, output current, and voltage. A general guideline is to choose a capacitor with a value between 10 nF to 100 nF.
• What is the maximum voltage rating of the IR2101PBF?
  The maximum voltage rating of the IR2101PBF is 600 V, but it can be operated up to 650 V with reduced performance.
