SLIS162H December 2014 – August 2018 DRV5013-Q1
The bypass capacitor should be placed near the DRV5013-Q1 device for efficient power delivery with minimal inductance. The external pullup resistor should be placed near the microcontroller input to provide the most stable voltage at the input; alternatively, an integrated pullup resistor within the GPIO of the microcontroller can be used.
Generally, using PCB copper planes underneath the DRV5013-Q1 device has no effect on magnetic flux, and does not interfere with device performance. This is because copper is not a ferromagnetic material. However, If nearby system components contain iron or nickel, they may redirect magnetic flux in unpredictable ways.
