IRS2108SPBF - Infineon

IRS2108SPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IRS2108SPBF?
  The IRS2108SPBF can operate up to 600 kHz, but it's recommended to operate it at 400 kHz or lower for optimal performance and to minimize EMI.
• How do I ensure the bootstrap capacitor is properly charged?
  The bootstrap capacitor should be charged through a resistor (typically 1 kΩ to 10 kΩ) connected between the bootstrap pin and the VCC pin. The capacitor value should be at least 10 nF to ensure proper charging.
• What is the recommended dead time for the IRS2108SPBF?
  The recommended dead time is typically around 100 ns to 200 ns, but it may vary depending on the specific application and switching frequency. A longer dead time can help reduce shoot-through currents, but may also increase switching losses.
• How do I protect the IRS2108SPBF from overvoltage and undervoltage conditions?
  The IRS2108SPBF has built-in overvoltage protection (OVP) and undervoltage protection (UVP) features. However, it's still recommended to add external protection circuits, such as a voltage supervisor or a crowbar circuit, to ensure the device is protected from voltage transients and faults.
• What is the maximum allowable voltage on the output pins (HO and LO)?
  The maximum allowable voltage on the output pins (HO and LO) is VCC + 0.3 V, but it's recommended to keep the output voltage within the VCC rail to ensure proper operation and to prevent damage to the device.
