UCC27524: Inquire driving capability for 12 MOSFETs in parallel

Part Number: UCC27524

Hi Sir,

May I learn from you if UCC27524 can drive 12pcs BSC010N04LS for 3.3kW design?

Thank you for your kindly help.

    Hello user,

    Thanks for your interest in our driver.

    BSC010N04LS looks like a 133nC gate charge FETs @ Vgs =10V. I presume you're driving 12 "BSC010N04LS" in parallel which will give a total gate charge of 12x133nC= 1596nC.

    Assuming your desired turn-on/off of the FETs dt = 500ns, you will require a driver capable of sourcing/sinking Ipk = dQ/dt = 1596nC / 500ns where Ipk = 3.192A.

    Each channel of the IC can source/sink peak currents up to 5A. For faster turn-on/off of the FETs, you can parallel the channels to double the drive current of the IC.

    If this addressed your questions, please press the green button or let us know if you have additional questions.

    Regards,
