SFFS141 December 2021 TCAN1167-Q1
The TCAN1167-Q1 monitors the VSUP supply rail for under voltage events (UVSUPF). If this threshold is crossed, the filter time (tUVFLTR) starts and must expire to be considered an under voltage event. A UVSUP event will cause the INH pin to turn off. When VSUP is greater than UVSUPR, the SWE timer will start as the device enters standby mode.
