Abstract
A device for recording the battery voltage in engine-control devices. The device has a first input terminal at which the battery voltage derived from the positive pole of the battery is supplied to the engine-control device. Moreover, it includes a first analog-digital converter and a first low-pass situated between the first input terminal and the first analog-digital converter. In addition, a first semiconductor switch is provided between the first input terminal and the analog-digital converter, which is conductive in the switched-on operation of the engine-control device and blocks in the switched-off operation of the engine-control device.
