3.7
Various comparators monitor the voltage in order to ensure error-free operation. The overvoltage must be active
at least 256 periods of t
suppression.

3.7.1
Every voltage regulator has an overvoltage (OV) comparator to detect a malfunction. If the nominal output voltage
of 2.5 V is larger than V

The Overvoltage Detection comparator monitors the external supply voltage at the V
bit
3.7.3
The GND - Off comparator is used to detect a voltage difference between the GND pin and SCK. It activates the
S_VR bit of the SSC Interface. This circuit can detect a disconnection of the supply GND pin.
