Current Shunt Resistor
If current shunt resistor is connected between GND_X to GND or PVDD_X to PVDD, make sure there is only one
single path to connect each GND_X or PVDD_X pin to shunt resistor, and the path is short and symmetrical on
each sense path to minimize the measurement error due to additional resistance on the trace.
PCB LAYOUT EXAMPLE
An example of the schematic and PCB layout of DRV8312 are shown in Figure 13, Figure 14, and Figure 15.
