Control unit with circuit and method for short-circuit protection of ground lines and sensors

摘要

Control unit (6) for evaluating the sensor signal of a sensor (2) comprising at least one first sensor connection (21) and a second sensor connection (22) for connecting the sensor (2), the second sensor connection (22) being connected to a short-circuit protection circuit (23) is, which is arranged between the second sensor terminal (22) and a ground (3) and which comprises a switchable transistor (7), with which the ground (3) of the second sensor terminal (22) can be interrupted.
