Low voltage detector electrical characteristics
The device implements a power-on reset (POR) module to ensure correct power-up initialization, as well as five low voltage
detectors (LVDs) to monitor the VDD and the VDD_LV voltage while device is supplied:
POR monitors VDD during the power-up phase to ensure device is maintained in a safe reset state (refer to RGM
Destructive Event Status (RGM_DES) Register flag F_POR in device reference manual)
LVDHV3 monitors VDD to ensure device reset below minimum functional supply (refer to RGM Destructive Event
Status (RGM_DES) Register flag F_LVD27 in device reference manual)
LVDHV3B monitors VDD_BV to ensure device reset below minimum functional supply (refer to RGM Destructive
Event Status (RGM_DES) Register flag F_LVD27_VREG in device reference manual)
LVDHV5 monitors VDD when application uses device in the 5.0 V ± 10% range (refer to RGM Functional Event Status
(RGM_FES) Register flag F_LVD45 in device reference manual)
LVDLVCOR monitors power domain No. 1 (refer to RGM Destructive Event Status (RGM_DES) Register flag
F_LVD12_PD1 in device reference manual)
LVDLVBKP monitors power domain No. 0 (refer to RGM Destructive Event Status (RGM_DES) Register flag
F_LVD12_PD0 in device reference manual)
