Abstract (en)

[origin: WO0214879A1] The invention relates to a circuit for detecting a current passing through a consumer (16), said consumer being located between the outputs (14c, 15c) of two amplifiers (14, 15) which have a supply voltage connection (14a, 15a) and an earth connection (14b, 15b) respectively, enabling the supply of a unipolar operating voltage. The invention is characterized in that a load resistor (17) is connected between the connection (18a) of the operating voltage source and the supply connection (14a, 15a) and/or between the earth connection (14b, 15b) and the earth (18b). A voltage UA which is proportional to the current to be detected is released at said load resistor.
