Abstract
A circuit for diagnosing the state of a load connected to a driver includes a DMOS transistor interposed between a terminal of the load and voltage comparator circuits. The DMOS transistor limits the maximum voltage input to the comparators to thereby reduce the circuit area occupied by the comparators and consequently to reduce the cost of the diagnosis circuit.
