Abstract
An electronic device includes a driver circuit embodied on an IC chip. The driver circuit includes a threshold voltage selection circuit that is coupled to receive a horn comparator threshold setting and to use the horn comparator threshold setting to provide a horn comparator threshold voltage. The driver circuit also includes a comparator that has a non-inverting input coupled to a first pin and an inverting input coupled to receive the horn comparator threshold voltage.
