PRODUCTION DATA
The device monitors VSUP for two low voltage thresholds, UVSUP and VnPOR. When VSUP drops below UVSUPF and is above VnPORF, the device is in an under-voltage power state. Once VSUP ramps above UVSUPR, the device enters restart mode and turns on the VCC LDO, see Restart Mode. When VSUP drops below VnPORF, the device goes into a power off state. Once VSUP ramps above VnPORR, the device prepares the digital core to wake up. The device waits for VSUP to rise above UVSUPR and then turns on the VCC LDO. Once VSUP and VCC are above their under-voltage levels, the device enters Init mode, see Init Mode. The described under-voltage events are also considered brown out events and more information can be found at Device Brownout information.
