IRS2101SPbF datasheet by International Rectifier

IRS2101SPbF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IRS2101SPBF?
  The IRS2101SPBF can operate up to 600 kHz, but it's recommended to operate at 400 kHz or lower for optimal performance and to minimize losses.
• How do I ensure proper bootstrap capacitor selection for the IRS2101SPBF?
  Choose a bootstrap capacitor with a voltage rating of at least 2x the maximum voltage of the high-side supply, and a capacitance value between 10nF to 100nF. Ensure the capacitor is placed close to the IC and has a low ESR.
• What is the recommended deadtime for the IRS2101SPBF?
  The recommended deadtime is typically between 100ns to 500ns, depending on the specific application and switching frequency. A longer deadtime can help reduce shoot-through currents, but may increase switching losses.
• How do I handle overcurrent protection with the IRS2101SPBF?
  The IRS2101SPBF has a built-in overcurrent protection feature that can be enabled by connecting the OC pin to a resistor and a capacitor. The recommended values for the resistor and capacitor can be found in the datasheet, and the threshold can be adjusted by changing the resistor value.
• What is the maximum allowable voltage on the VCC pin of the IRS2101SPBF?
  The maximum allowable voltage on the VCC pin is 15V, but it's recommended to keep it below 12V to ensure reliable operation and minimize power consumption.
