Abstract

The present invention relates to a device (30) for powering an electronic control unit (2) comprising a first connection terminal (26_1) coupled to an electrical power supply (10), a second connectionterminal (26_2) coupled to an electrical ground (32), a microprocessor (22) having a microprocessor power supply input (22_1) that is coupled, on the one hand, to a first terminal of first capacitor(C3_1) with a first capacitance (C_3) and, on the other hand, coupled to a power supply output (30_1) of the power supply device (30), the second terminal of first capacitor (C3_2) being coupled to the electrical ground (32), the power supply device (30) comprising a first power supply input (30_2) characterized in that it comprises a diode (36) coupled to the power supply input (30_2) and to thepower supply output (30_1), and a switching device (38) simultaneously coupled to the diode (36).

Description

technical field [0001] The present invention relates generally to the feeding of electrical power to electronic devices, such as electronic computers. [0002] The invention is particularly applicable in the field of motor vehicles. The invention can be implemented, for example, in an engine control electronic computer. Background technique [0003] Motor vehicles today include an increasing number of on-board electronic devices. Thus, in motor vehicles, several electronic computers are used to ensure the safety of the driver, the ventilation in the cabin or the operation of the internal combustion engine. [0004] Electronic computers comprise a relatively large number of passive electronic components (resistors, capacitors, inductors) or active electronic components (microprocessor(s), memory) arranged by means of printed circuits and / or or electrical traces in printed circuits for coupling. [0005] The relatively large number of electronic computers and also power co...
