3.7.2 Voltage monitor electrical characteristics
The device implements a Power-on Reset (POR) module to ensure correct power-up initialization, as well
as four low voltage detectors (LVDs) to monitor the V_DD and the V_DD12 voltage while device is supplied:
• POR monitors V_DD during the power-up phase to ensure device is maintained in a safe reset state
• LVDHV3 monitors V_DD to ensure device reset below minimum functional supply
• LVDHV5 monitors V_DD when application uses device in the 5.0 V ± 10% range
• LVDLVCOR monitors power domain No. 1
• LVDLVBKP monitors power domain No. 0
