An information processing system has a plurality of processor circuits, each of the processor circuits including internal circuits and an internal processing result outputting circuit, the system having an internal data selection circuit connected to each of the processor circuits and at least one fault detection circuit. The internal processing result outputting circuit of each of the processor circuits outputs respective ones result data processed by respective ones of the internal circuits in the processor circuit. Each of the internal data selection circuit selects and outputs one selected result data output from the internal processing result outputting circuit of each of the processor circuits, at a predetermined timing. The fault detection circuit outputs a result of a comparison among the data selected by the respective internal data selection circuits of the processor circuits or among the data output at each predetermined timing by the processor circuits.

This invention provides a current control semiconductor element in which dependence of a sense ratio on a temperature distribution is eliminated and the accuracy of current detection using a sense MOSFET can be improved, and to provide a control device using the current control semiconductor element. The current control semiconductor element 1 includes a main MOSFET 7 that drives a current and a sense MOSFET 8 that is connected to the main MOSFET in parallel and detects a current shunted from a current of the main MOSFET. The main MOSFET is formed using a multi-finger MOSFET that has a plurality of channels and is arranged in a row. When a distance between the center of the multi-finger MOSFET 7 and a channel located farthest from the center of the multi-finger MOSFET 7 is indicated by L, a channel that is located closest to a position distant by a distance of (L/(√3)) from the center of the multi-finger MOSFET is used as a channel for the sense MOSFET 8.

An electronic control apparatus includes a control unit 2; a plurality of power supply units 1-1, 1-2 for supplying the control unit 2 with power; and a power supply fault detector unit 3 for detecting a fault in the plurality of power supply units 1-1, 1-2. The control unit 2 operates in a normal mode on electric power supplied from the plurality of power supply units 1-1, 1-2, when none of the plurality of power supply units 1-1, 1-2 is faulty. If at least one of the plurality of power supply units 1-1, 1-2 is faulty, the control unit 2 operates in an energy saving mode in which less power is consumed on electric power supplied from the power supply unit that remains fully operational. Thereby an electronic control apparatus is obtained that enables continued operation during a faulty condition, while preventing circuit scale, dimensions, weight, and cost from increasing.
