Fault detection method for output stage circuit arrangement

The method involves connecting a load to a supply potential via a first switch (110), and to ground via a second switch (120). A specific voltage is developed at a connection point between the first switch and the load, and is evaluated for detecting a fault. The first switch and/or the second can b...

Zusammenfassung:	The method involves connecting a load to a supply potential via a first switch (110), and to ground via a second switch (120). A specific voltage is developed at a connection point between the first switch and the load, and is evaluated for detecting a fault. The first switch and/or the second can be set in a defined state, and the voltage at the point of connection between the first switch and the load can be compared with the reference voltages to detect a fault. The time that the switches are held in a defined state can be so short that the switching state of the load is not changed. It can be arranged that a change in the switching state of the load can take place only if no fault is detected.
