Abstract (en)
[origin: WO2013072385A1] The invention relates to a device and a method for testing the connection of a load (L) connected to a connection point (1). The connection point (5) is formed between a first switching element (HS), which is connected between a high supply voltage potential (VDD5_IGN) and the connection point (5), and a second switching element (LS), which is connected between the connection point (5) and a low supply voltage potential (⊥). When the two switching elements (HS, LS) are switched off, a potential is built up at the connection point (5) by means of at least one voltage or current source (3) connected to the connection point (5), and a potential analyzing circuit (4) checks whether the potential (VOUT) lies in a defined potential range. If this is the case, it is concluded that a line between the connection point (5) and the load (L) has been interrupted.
