<p>A detection circuit is coupled to an output terminal of a driver circuit. The detection circuit includes a comparator to compare a signal at the output terminal to a reference signal corresponding to a signal that would be generated if a capacitive load having a relatively high capacitance value were connected to the output terminal. Output of the comparator is sampled at a predetermined time after the driver circuit provides the drive signal. An error signal is generated when the sampled output indicates that the capacitive load having the relatively high capacitance value is actually connected to the output terminal.</p>
