I am working on duplicating a product according to the Microchip datasheet. http://ww1.microchip.com/downloads/en/appnotes/00857b.pdf My question has to do with something I found in the schematic (page 29, and also inserted below). That is, the bypass circuitry at supply of each of the two main drivers appears to have a path straight to ground from +12V (see below). How will this power the drivers at all connected like this??? I figure I am just understanding this wrong and it is not a typo because its coming from Microchip and not some Joe-Schmo. Can someone explain this to me? Thanks in advance.
The connection from pin 14 to the bottom of cap C2 should not be there. Also, the link in the original post is to an Application note, and not a datasheet. The TC4469 datasheet http://ww1.microchip.com/downloads/en/DeviceDoc/21425C.pdf has the 3B, 4B, pins labelled correctly and Figure 4-1 shows the proper GND connection for the caps.
Yes, this is definitely wrong. You could try emailing Microchip with the correction, but it's a pretty old document so they probably won't bother doing it.
nothing not much wrong with the schematics, if the attention is at the pointed arrow. Some schematics drawing tools do use the solid bar symbol as power rail:
The GND usually have striped shape, or triange, or other shapes that are meant to differentiate between signal ground, power ground, analog ground, and shields.
However, the OP marks wrong spot on the drawings. One wire is obviously wrong, I agree:
