Re: Self-Resonant Driver Boards (DRSSTC, ISSTC, etc...) Bulk Purchase ? ? ? ? Anyone ? ? ?

Good, because the way you had put it,  it seemed as though the circuit was
only to protect the driver chips and not the transistors in the bridge,  I
guess that would go hand in hand though...

It might be wise to allow some sort of heatsinking on the driver chips,
incase they would get warm,  But if you're using the UCC27321,  I don't
think that would be needed, as they have a wider temperature operating
range.
