ABSTRACT:
Pin-driver circuitry in each of an automatic circuit tester (10)'s digital driver/sensor circuits (36) includes a current sensor (R.sub.sense, QS1, QS2, D1, and D2) and comparison circuit (58) that indicate whether the load current supplied by the driver exceeds a level set by a threshold input (CURRENT.sub.-- VALUE). The pin-driver circuitry also includes a timer (60) whose output indicates whether the comparison circuit's output has been asserted for a length of time that exceeds a limit set by a duration input (TIME.sub.-- -VALUE). When it has, the tester disables the driver and thereby prevents damage that could otherwise result from excessive backdrive durations that the test-generation process did not anticipate.
