JAJSNV0B December 2022 – August 2024 TMAG5115
PRODUCTION DATA
TI recommends placing the bypass capacitor near the TMAG5115 device for efficient power delivery with minimal inductance. TI recommends placing 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, using PCB copper planes underneath the TMAG5115 device has no effect on magnetic flux and does not interfere with device performance. This is because copper is not a ferromagnetic material. However, nearby system components that contain iron or nickel can redirect magnetic flux in unpredictable ways.
