  • RE: DRV8874: Current chopping turn-off much slower than tDEG spec

    Resolved
    Pablo Armet said: The diagram in the datasheet does not show the extra time required for the driver to go into decay mode. Then the diagram is wrong, isn't it?

  • DRV8874: DRV8874 as bus converter driver

    TI Thinks Resolved
    Part Number: DRV8874 Other Parts Discussed in Thread: DRV8873 , Need to construct a bus converter that takes Vin = 15V and outputs 60V or 75V depending on the turns ratio of the transformer. Would operate the DRV8874 in EN/PH mode, driving PH with 50%…
