PRODUCTION DATA.
A short to VBAT_IN fault occurs when the difference between the voltage measured for the VBAT_IN pin and the input pin, ABS(VBAT_IN – INxx), is less than the threshold or both the VBAT_IN and INxx pin measured voltages are above 11.7 V. The threshold can be set by configuring DIAG_SHT_VBAT_IN, P0_R101_D3-0.
When VBAT_IN is less than MICBIAS, false fault detections can exist based on the signal level of the INxx pin. To minimize false detections there is also a separate debounce count for this condition set by configuring VSHORT_DBNCE, P0_R106_D1.
