Hi,

I couldn't find a current spec for the V3P3 pin on the DRV8823. How much current can it safely source?

Thanks,

Rob

Rob,

Sorry this is missing from the datasheet.

We typically specifiy 1mA as a max which is enough to source logic pins and references (like ABREF and CDREF), but certainly not enough to drive external microprocessors our other circuitry that would exceed the 1mA range.
