12 years ago --- Quote Start --- I attached picture of schematic --- Quote End --- The SENSE_PAD is a 2-pin component. You'll need to look in the PCB layout to see what those correspond to. Most likely they are just a copper shape, eg., the Kelvin sense connections to the current-sense resistor, or test-points. Its quite common to see parts in schematics that correspond to PCB structures that do not have physical components. For example, I've seen 0102 sized components that are used to short signals together, eg., an 0102 PCB footprint with a short between the two pads. This allowed the board to be loaded with 0-ohm resistors by default, but allows the end user to cut that trace to remove the (non-existent) 0-ohm resistor, or to add a different value. Its much nicer to "see" this component in the schematic, rather than it be some "magic" hidden in the PCB layout. Cheers, Dave
