UCC27531: Miller clamp for non-isolated gate drivers

Part Number: UCC27531

Customer using miller clamp for isolated gate drivers.

If they need non-isolated gate drivers, are they any non-isolated gate drivers with miller clamp?

    Hi Eddie,

    We do not currently have any non-isolated drivers with miller clamp. The closest thing available would be to use a strong driver with split outputs like UCC2753x family. A low impedance on OUTL should allow the driver to sink larger miller currents with less voltage rise.

    If the VDD requirements are not very high, some of the low-side LM51xx family may work. LM5112 has a negative rail which can help mitigate miller turn-on. LM5134's complimentary output is similar to an external miller clamp. 

    Thanks,

    Alex M.
