A method for operating a control unit for an exhaust gas probe, in particular a broadband Lambda probe for an internal combustion engine, in particular of a motor vehicle. The control unit is designed for the electrical actuation of the exhaust gas probe, and the control unit in particular being implemented in the form of an application-specific integrated circuit, ASIC. The method includes: specifying control data for an operation of the control unit and/or the exhaust gas probe with the aid of a processing device; receiving operating data which characterizes the operation of the control unit and/or the exhaust gas probe with the aid of a processing device.

A method includes determining a first voltage that is in a high-side path of a circuit, the path including a high-side switch connected between a first potential connection of the circuit and a first connection of a load of the circuit; determining a second voltage that is in a low-side path of the circuit, the path including a low-side switch connected between a second potential connection of the circuit and a second connection of the load; responsive to a determination that one of the voltages exceeds a threshold for at least a duration of a predefined time interval, checking whether the other voltage currently exceeds the threshold; and determining that there is a short circuit across the load or in whichever of the paths has the voltage that exceeded the threshold for the duration, respectively, if the result of the check is positive or negative.

Method for detecting a short circuit across a load

A method for transferring data from an actuating element to a control unit activating the actuating element. The control unit activates an inductance contained in the actuating element, for the transfer of the data in the actuating element in parallel to the inductance, a load being connected in parallel, or not.

A circuit for detecting a creeping short circuit in bridge connections. The circuit includes a first detection device for a power loss at a battery-side connection of the bridge connection to a first counting register and a second detection device for a power loss at a ground-side connection of the bridge connection to a second counting register.
