IR2108SPBF Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the IR2108SPBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
  • To ensure the bootstrap capacitor is properly charged, make sure to provide a low-impedance path from the bootstrap pin to the high-side supply voltage (VCC) and use a capacitor with a sufficient capacitance value (typically 1-10 nF).
  • The SD (Shutdown) pin is used to disable the device and reduce power consumption. To use it, connect the SD pin to a logic low signal to shut down the device, and connect it to a logic high signal or leave it open to enable the device.
  • To handle the dead time, use the dead-time control pins (DT_Ctrl) to adjust the dead time between the high-side and low-side switches. The dead time can be set between 100 ns to 1.5 μs using an external resistor and capacitor.
  • For optimal performance, use a 4-layer PCB with a solid ground plane, keep the high-current paths short and wide, and use a Kelvin connection for the high-side and low-side switches. Also, place the bootstrap capacitor close to the IC and use a low-ESR capacitor for the VCC bypass.
