Abstract

See full text

A device measures the current in an inductive load using two separate current-measuring paths to detect the current in the inductive load. The inductive load is connected between first and second nodes, and the first node connected to a first voltage. The device includes first and second transistors cascaded together between the first node and a third node that is connected to a second voltage. First and second sense amplifiers measure the current in the inductive load. The first and second sense amplifiers are connected to at least one terminal of the first and second transistors. Two blocks sample and hold signals from the first and second sense amplifiers, which represent, respectively, the currents in the two separate current-measuring paths. The two currents are subtracted in a comparison node for generating an error signal that is compared with a predefined window and if outside the window a failure signal is generated.
