ZHCSHJ5 December 2018 DRV5021
PRODUCTION DATA.
Place the bypass capacitor near the DRV5021 device for efficient power delivery with minimal inductance. Place the external pullup resistor 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, PCB copper planes underneath the DRV5021 have no effect on magnetic flux, and do not interfere with device performance because copper is not a ferromagnetic material. However, If nearby system components contain iron or nickel, they may redirect magnetic flux in unpredictable ways.
