IR2113 datasheet by International Rectifier

IR2113 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VCC pin?
  The maximum voltage that can be applied to the VCC pin is 20V, but it's recommended to keep it between 10V to 15V for optimal performance.
• How do I ensure proper bootstrap capacitor selection?
  The bootstrap capacitor should be selected based on the maximum voltage and current requirements of the high-side driver. A general rule of thumb is to choose a capacitor with a voltage rating of at least 2x the maximum voltage of the high-side driver and a capacitance value of 10nF to 100nF.
• What is the purpose of the VSS pin, and how should it be connected?
  The VSS pin is the substrate connection of the IC and should be connected to the negative rail of the power supply or the source of the low-side FET. This helps to reduce noise and improve the overall performance of the driver.
• How do I prevent shoot-through current when using the IR2113?
  Shoot-through current can be prevented by ensuring that the dead-time between the high-side and low-side drivers is sufficient. The dead-time should be at least 100ns to 200ns to prevent both FETs from conducting simultaneously.
• What is the recommended layout and PCB design considerations for the IR2113?
  The IR2113 requires careful PCB design and layout to minimize noise and ensure proper operation. Keep the high-current paths short and wide, use a solid ground plane, and separate the high-side and low-side circuits to reduce noise coupling.
