Voltage monitor electrical characteristics
The device implements a power on reset module to ensure correct power-up initialization, as well as three 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
LVDHV5 monitors VDD when application uses device in the 5.0 V ± 10% range
LVDLVCOR monitors low voltage digital power domain

Power up/down sequencing
To prevent an overstress event or a malfunction within and outside the device, the MPC5602P implements the following
sequence to ensure each module is started only when all conditions for switching it ON are available:
A POWER_ON module working on voltage regulator supply controls the correct start-up of the regulator. This is a
key module ensuring safe configuration for all voltage regulator functionality when supply is below 1.5 V. Associated
POWER_ON (or POR) signal is active low.
