    Maximum current of IR2110


    This is kind of a silly question but, i need to design an h bridge for a motor of 10A and 48V.

    Accordding to the datasheet the maximum current the IR2110 is capable of delivering its just 2.5A.

    So my question is, this current is just the current for turning on and off the mosfets not the current going through the MOSFETS, right?

    Any advice on how to design the bridge?

    Thank you in advance.

    Hi Xavier,

    Welcome to the forum.
    you guess correctly. the gate driver current is the current that the gate driver can deliver to the MOSFET gate terminal for turn-on/off.
    if you go on the Infineon webpage for the gate driver on the right we have a tool to help you select a MOSFET:
    We cannot recommend a specific MOSFET as you need to better understand what are your design constrains and want you to achieve with your H-bridge.
    So I recommend reading a few of our applications notes. A good start for MOSFETs is: then you can continue with the references on the last page.
    Generally, you want to keep the operating voltage at max ~60% of the MOSFET breakdown voltage (especially if you have a non-optimized layout - or are new to this).
    Also, maximum current is generally only for orientation, and MOSFETs are generally not recommended to operate at max current due to degradation and thermal contraints.
