Abstract
A circuit arrangement for bidirectional current limiting comprises a first transistor, a second transistor, a first resistor, a first zener diode and a second zener diode. The first transistor comprises a first controllable path and a first control terminal and the second transistor comprises a second controllable path and a second control terminal. The first and the second control terminals are connected to a first current source and the first resistor is connected between the first and the second controllable paths. The first zener diode is connected between the first current source and a first line node which is located between the first controllable path of the first transistor and the first resistor. The second zener diode is connected between the first current source and a second line node which is located between the second controllable path of the second transistor and the first resistor. The first and second controllable paths and the first resistor are connected between first and second terminals of the circuit arrangement.
