Abstract: A driving protection circuit is coupled to a load via an input/output pin. A signal generator circuit is configured to generate a driving signal. An input/output circuit transmits the driving signal to the input/output pin according to an enable signal. A counter circuit adjusts the count value when the enable signal is at a predetermined level. A detection circuit detects the voltage level of the input/output pin to generate a detection signal. When the count value is equal to a predetermined value, a control circuit determines whether the level of the detection signal is the same as the level of the driving signal. When the level of the detection signal is not the same as the level of the driving signal, the control circuit sends an error signal to turn off power to the load.

Abstract: A skate on a tip of a probe for testing electrical devices is a reduced thickness probe tip contact. Such a skate can advantageously increase contact pressure, but it can also undesirably reduce probe lifetime due to rapid mechanical wear of the skate. Here multilayer skate probes are provided where the overall shape of the probe tip is a smooth curved surface, as opposed to the conventional fin-like skate configuration. The skate layer is the most mechanically wear-resistant layer in the structure, so abrasive processing of the probe tip leads to a probe skate defined by the skate layer. The resulting probes provide the advantage of increased contact pressure without the disadvantage of reduced lifetime.
