UCC27200: Mismatch time of UCC27200

Part Number: UCC27200
Other Parts Discussed in Thread: UCC27282

Hi team,

If I have several gate drivers of UCC27200, the input of these UCC27200 are all from the same PWM signal.

Due to the delaying matching, it might be have inconsistency of these output signals. I just called it mismatch between drivers.

How can I judge the mismatching between different output signals from different drivers?

Do you have any devices to recommend with lower mismatching time such as UCC27200?

Best Regards,


  • Hello Xing,

    What is the duration of the mismatch that you're currently observing? Do the different IC's have similar symmetrical signal paths? I ask because PCB layout specifically trace length of PWM signal is generally a contributing factor. 

    If possible, you may share your schematic and/or layout for further review.

    Meanwhile UCC27282 might be a good alternative option with difference 5V UVLO difference and the added benefit of interlock feature preventing both HO and LO simultaneously being high.
