Drive current capability for AduM4135

Category: Hardware

Adum4135: what is the peak output current at 45kHz. datasheet says 4A, AN-1536 7A and CREE use it at 10A (CGD1200HB2P-BM3). Of course it depends on gate capacitance and frequency but is it a limit when the driver saturates and loss in Adum will be to high?

    Hi  ,

    The peak output current is mainly limited by the output resistance or the gate resistance. Yes, the typical peak output current for the ADuM4135 is 4A - this is with 2ohm of gate resistance…
