1.3 Power Management
The KM power management provides the items as follows:
Power Protection to be compliant E-mark;
Voltage Regulators to feed the different modules;
Slope Voltage Detector implemented only via Hw components;
Power backup management, the power back-up could be implemented via battery back-up or super-cap;
Voltage and temperature measurements for battery back-up management;
Voltage measurements of the vehicle battery.

The KM power management permits to cut off the battery back-up, if any, in order to switch off completely
the board in case of absence of vehicle battery (transport mode), and permits an HW restart via signal from
MCU/GNSS (power cycle)
