PRODUCTION DATA
The ramp amplitude, soft-start time, and current limit settings are programmed with a single resistor, RMSEL, from MSEL to AGND. Table 6-5 lists the resistor values for the available options. Use a 1% tolerance resistor or better. See Section 6.3.11.1 for the corresponding current limit thresholds for the "High" and "Low" settings.
