Abstract
A load driver circuit (10) includes an output driver (11) suitable for driving an inductive load (13). An output clamp circuit (15) clamps the output (12) to a high voltage during turn-off of the output driver (11). An open load detect circuit (26) clamps the output (12) to a lower voltage when the load (13) has an open circuit fault. A power fault voltage detect circuit (28) clamps the output (12) to another low voltage during a power fault condition.
