8.3.4 Overvoltage Protection

If, for any reason, the output voltage is not fed back properly to the input of the voltage amplifier, control of the output voltage no longer works. Therefore, overvoltage protection is implemented to avoid the output voltage exceeding critical values for the device and possibly for the system it supplies. The implemented overvoltage protection circuit monitors the output voltage internally as well. If it reaches the overvoltage threshold, the voltage amplifier regulates the output voltage to this value.
