Voltage monitor electrical characteristics

The device implements a Power-on Reset module to ensure correct power-up initialization, as well as four low voltage detectors

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

•

LVDHV3 monitors VDD to ensure device reset below minimum functional supply

•

LVDHV3B monitors VDD_BV to ensure device reset below minimum functional supply

•

LVDHV5 monitors VDD when application uses device in the 5.0 V ± 10% range

•

LVDLVCOR monitors power domain No. 1

•

LVDLVBKP monitors power domain No. 0

NOTE

When enabled, power domain No. 2 is monitored through LVD_DIGBKP.
