3.11
Various comparators monitor the voltage in order to ensure error-free operation.
The overvoltages must be active for at least t
works as digital spike suppression.
Table 20
3.11.1
Every voltage regulator has an overvoltage comparator to detect a malfunction.
If the nominal output voltage of 2.5 V is larger than V
activated. It sets the VRx_O V bit.

3.11.2
The Overvoltage Detection Comparator monitors the external supply voltage at the V
STAT_VR (see
3.11.3
The GND-off Comparator is used to detect a voltage difference between the GND pin and TST1 (which must be
soldered to GND in the application). It activates the STAT_VR bit. This circuit can detect a disconnection of the
Supply GND Pin.
