Selecting the right gate driver

How do I know if the gate driver I selected for my design will be able to drive the load presented?

  • The key specifications that you should always consider when looking at the drive capability of the gate driver are

    • the edge rates required
    • the operating frequency needed
    • and the load that must be driven
    • as well as the voltage levels that you need to drive to.

    Knowing these variables will help to understand the thermal dissipation which can sometimes become the limiting factor in the design.

    The quickest way to figure out if a particular gate driver will support your design is to compare the Rdson of the driver. The lower this value is better
