Summary: | The invention relates to a voltage supply for a sensor unit, particularly an acceleration sensor unit in an occupant protection system in a motor vehicle, with a voltage supply unit which operates at an internal switching frequency having a capacitor connected in parallel with the output, with a sensor unit which operates at an internal switching frequency and having at least one capacitor connected in parallel with the power supply input, with a line connecting the output of the voltage supply unit to the power supply input of the sensor unit and with a filter having a filter component contained between the branch points of the capacitors in the line.
A voltage supply unit which operates at an internal switching frequency and has a capacitor connected in parallel with its output is connected to the input of a sensor unit operating at an internal switching frequency. The connecting line contains a resistor which, together with a capacitor connected in parallel with the input, forms a filter. |
