Abstract

The invention relates to a current mirror arrangement for monitoring a bidirectional current in a signal path. The arrangement comprises a first semiconductor switch (2) with a control electrode (3) and main current path electrodes (4, 5). The arrangement further comprises a resistor (R1) arranged between the control electrode (3) and the signal path (1), a resistor (R3) arranged between a main current path electrode (4) and the signal path (1), and a resistor (R2) arranged in the signal path (1). The current mirror arrangement further comprises a second semiconductor switch (6) which comprises a control electrode (7) and main current path electrodes (8, 9) connected to the first semiconductor switch (2) in the signal path (1) to implement a bipolar current mirror function irrespective of the direction of the current (1x) in the signal path (1). <IMAGE>
