IR2104STRPBF datasheet by International Rectifier

IR2104STRPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR2104STRPBF?
  The maximum operating frequency of the IR2104STRPBF 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 is enabled before the low-side driver, and the bootstrap capacitor should be at least 10 times the gate charge of the high-side MOSFET.
• What is the recommended dead time between the high-side and low-side drivers?
  The recommended dead time between the high-side and low-side drivers is typically around 100-200 ns to prevent shoot-through current.
• How do I handle the undervoltage lockout (UVLO) feature?
  The UVLO feature is enabled by default, and it can be disabled by connecting the UVLO pin to VCC. If enabled, the device will shut down if the supply voltage falls below 7.5V.
• What is the maximum allowable voltage on the VCC pin?
  The maximum allowable voltage on the VCC pin is 15V, but it's recommended to keep it below 12V for reliable operation.
