Abstract
A control unit for personal protection having a polarity reversal protection between an external battery voltage and an internal voltage, to prevent an energy discharge from the control unit. The control unit also has a bidirectional DC/DC converter between an energy reserve and the internal voltage, the DC/DC converter determining its direction of conversion as a function of the internal voltage. The control unit is configured so that the control unit, after a switching-off process, records at least one measured value and generates a signal as a function of this measured value which characterizes an autarchy behavior of the control unit.

A control unit for personal protection comprising:
- a control unit arrangement having a polarity reversal protection arrangement, between an external battery voltage and an internal voltage, to prevent an energy discharge;
- and
- a bidirectional DC/DC converter, between an energy reserve and the internal voltage, to determine its direction of conversion as a function of the internal voltage;
- wherein the control unit arrangement is configured so that, after a switching-off process, the control unit arrangement records at least one measured value and generates a signal as a function of this measured value which characterizes an autarchy behavior of the control unit arrangement.
