Abstract
A device includes a driver circuit and diagnostic circuitry coupled to the driver circuit. The diagnostic circuitry includes an on-state diagnostic circuit and an off-state diagnostic circuit. The diagnostic circuitry, in operation: generates a configuration signal associated with an operative condition of the driver circuit based on a comparator output of the off-state diagnostic circuit; diagnoses conditions associated with the driver circuit; and controls operation of the on-state diagnostic circuit based on the configuration signal.
