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_HV_A and the VDD_LV voltage while device is supplied:
POR monitors VDD_HV_A during the power-up phase to ensure device is maintained in a safe reset state
LVDHV3 monitors VDD_HV_A to ensure device is reset below minimum functional supply
LVDHV5 monitors VDD_HV_A when application uses device in the 5.0 V±10% range
LVDLVCOR monitors power domain No. 1 (PD1)
LVDLVBKP monitors power domain No. 0 (PD0). VDD_LV is same as PD0 supply.
NOTE
When enabled, PD2 (RAM retention) is monitored through LVD_DIGBKP.

DD_HV_A = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified.
2 All values need to be confirmed during device validation.
3 Assumption is V
DD_HV_A is now supplying the external ballast. This current is the ballast inrush current.
4 Inrush current is seen more like steps of 600 mA peak. The startup of the regulator happens in steps of 50 mV in
~25 steps to reach ~1.2 V VDD_LV. Each step peak current is within 600 mA
