7 CS, RMP, and ADV Resistor Selection

Note that the three pins, CS, RMP, and ADV, are used to configure settings for the DRV10974 device. The receptacles (J10, J9, and J8) on the CS, RMP, and ADV pins are used for installing axial-lead, through-hole resistors to quickly configure settings on the DRV10974EVM. Note that R6, R7, and R8 are 0402, 0-Ω surface-mount resistors in series with the receptacles. They give the user flexibility to achieve the desired resistor values if necessary.

In addition, the 0603 surface mount resistors (R4, R3, and R2) can also be replaced or removed to configure the settings. Because these resistors are populated by default, it is highly recommended to remove these resistors or to calculate the parallel resistance if the receptacles are used. This is shown in Figure 13. See the DRV10974 Tuning Guide for more information.

Furthermore, ensure all resistors have 1% tolerance for CS, RMP, and ADV pins.
