UCC21231: UCC21231

Part Number: UCC21231

Tool/software:

Hi we are designing a product where we need to drive a transformer to drive that we need 2 low side mosfet drivers with adjustable dead time control and also the mosfet should also be integrated wihin the driver below are the details of specifications. The above part no is the reference what we require but it doesn't meet other specifications so kindly see the below info.

  • Product is used for a skin treatment. The “Load” here is the human skin. The output voltage and power shall be delivered to human skin via a micro-needles.  
  • Hi Apoorva,

    the mosfet should also be integrated wihin the driver

    Is it correct to say that you are looking for MOSFETs with integrated gate drivers?

    Just want to clarify what type of product you are looking for.

    For our isolated gate drivers, these will be external gate drivers that connect externally to discrete MOSFETs or modules.

    Looking forward to hearing back.

    Regards,

  • Hi Hiroki,

    Yes, we are looking for MOFETs with integrated gate drivers also including dead time control.

    Also below is the application how we want to use it for.

    A common approach for this application is to drive a transformer primary with a square wave of 1MHz and feed secondary output to end use. We are open to evaluate any suitable solution you may have including but not limited to the following 

    • Integrated device with dual low side switch, gate driver & dead time control (To drive transformer) 
    • Integrated device with H-bridge switches, gate driver & dead time control (To drive transformer) 
    • Any other solution topology & suitable devices which could meet the requirement. 
  • Hi Apoorva,

    Appreciate the follow up!

    I am not best contact to comment on the MOSFET/power stage solutions that we have, since I am primarily responsible for our dual-channel isolated gate driver portfolio. However, you can check out the integrated power stages here:

    For specific questions on these products, please post another thread and the correct technical expert will help support.

    Thank you!

    Regards,

    Hiroki
