Abstract

A personal protection control unit, having an energy reserve which is charged by a battery voltage and supplies power to the control unit. In addition, a first voltage supply circuit is provided, down-converting the voltage of the reserve power in such a way that the first voltage supply circuit supplies several voltage levels for operation of the control unit. Finally, a second voltage supply circuit is also provided and is also connected to the energy reserve, supplying at least one additional voltage level to at least one transistor and to at least one voltage regulator via a resistive circuit.
