IR2130S - Infineon

IR2130S Frequently Asked Questions (FAQs)

• What is the maximum voltage rating of the bootstrap capacitor?
  The maximum voltage rating of the bootstrap capacitor is 30V, but it's recommended to use a capacitor with a voltage rating of 35V or higher to account for voltage spikes.
• How do I ensure proper thermal management of the IR2130S?
  Proper thermal management can be achieved by providing a good thermal path from the device to a heat sink or the PCB, using thermal vias, and ensuring good airflow around the device. The maximum junction temperature (Tj) is 150°C.
• What is the recommended dead time for the IR2130S?
  The recommended dead time for the IR2130S is typically between 100ns to 500ns, depending on the specific application and switching frequency. A longer dead time can help prevent shoot-through currents, but may also increase switching losses.
• Can I use the IR2130S with a different voltage supply for the high-side and low-side drivers?
  Yes, the IR2130S can be used with different voltage supplies for the high-side and low-side drivers, but the voltage difference between the two supplies should not exceed 15V. Additionally, the voltage supply for the high-side driver should be higher than the voltage supply for the low-side driver.
• How do I protect the IR2130S from overcurrent and overvoltage conditions?
  The IR2130S has built-in overcurrent protection, but it's still recommended to use external overcurrent and overvoltage protection circuits to ensure the device is protected from fault conditions. A fuse or a current sense resistor can be used to detect overcurrent conditions, and a voltage supervisor can be used to detect overvoltage conditions.
