IR2156STRPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR2156STRPBF?
  The maximum operating frequency of the IR2156STRPBF is 500 kHz, but it can be extended up to 1 MHz with proper design and layout considerations.
• How do I ensure proper bootstrap capacitor selection for the IR2156STRPBF?
  The bootstrap capacitor should be selected based on the maximum operating frequency, voltage rating, and ESR (Equivalent Series Resistance). A general rule of thumb is to choose a capacitor with a value between 10nF to 100nF, and a voltage rating of at least 2x the maximum voltage of the high-side driver.
• What is the recommended dead-time between the high-side and low-side drivers of the IR2156STRPBF?
  The recommended dead-time between the high-side and low-side drivers is typically around 100-200 ns, but it can vary depending on the specific application and switching frequency. A longer dead-time can help prevent shoot-through currents, but may also increase switching losses.
• How do I protect the IR2156STRPBF from overvoltage and undervoltage conditions?
  The IR2156STRPBF has built-in undervoltage lockout (UVLO) protection, but it's still recommended to add external overvoltage protection (OVP) and undervoltage protection (UVP) circuits to ensure the device operates within its specified voltage range.
• What is the maximum allowable voltage difference between the high-side and low-side drivers of the IR2156STRPBF?
  The maximum allowable voltage difference between the high-side and low-side drivers is typically around 600V, but it's recommended to keep the voltage difference below 500V to ensure reliable operation and prevent damage to the device.
