A circuit for detecting a defect of electronic components in an electronic control unit includes an output for driving a load ( 3 ). A redundant measurement of the current (I L ) is executed at the contacts (G, S, D), in particular at the driven contacts (S, D), of one or more semiconductor circuit elements, and an error function of a semiconductor circuit element is detected when the comparison of two current values (I S , I Sense1 , I Sense2 ) by way of the current flowing through a load ( 3, 3 ′) indicates an unequal current distribution. This circuit is of use in electronic brake force or driving dynamics controllers for motor vehicles. |
