• What is -RL7 Suffix on ADUM3221?

    In its data sheet I notice that the ADUM3221 galvanically isolated MOSFET gate driver has a version with -RL7 suffix.   What is the significance of the -RL7 suffix?

  • ADUM1234 and ADUM3221 Input Signal Rise and Fall Times

    Hello,

    What happens if the rise/fall time of the input signal for the ADUM3221 or ADUM1234 is longer then the recommended maximum in the datasheet?

    Will it just possibly oscillate until it reliably gets out of the hysteresis zone?

    Will it reliably hold…

    Hi,

    Do you have this spice model for ADuM3221 available? 

    Thanks & Regards,

  • RE: The usage of ADuM3221

    With ref to the above attache schematic,  how high can the Vin be on the Q1 side? 

    Can I do 270VDC = Vin  assuming the FET is rated for this? 

    What is a practical limit for the working isolation voltage (Vin bus) on the ADum3221 in such a scenario as shown…

  • ADUM3221 Feasibility to drive load

    Hi, Everyone.

    I'm trying to use ADUM3221 to drive mosfet as below.

    Two questions :

    Q1. Can ADUM3221 drive MOSFETs as attached?(BTS5200, IRF7341)

    Q2. Continuous Current value? (IF VIA is  always high, how much current can be drown on VOA)

    Can It…

  • RE: ADuM3221 to drive a brushed motor

    For the second part of my answer, I did mean A4953, sorry for the confusion.

    The output voltages would be the supply voltage for the ADuM3220, but since this would be an output, a simple voltage divider would suffice to get the voltages in range for…
