Abstract

An electronic circuit includes a first transistor device with a control terminal and a load path. A drive circuit includes an input terminal and an output terminal. The output terminal is coupled to the control terminal of the first transistor device. The drive circuit is operable to drive the first transistor device dependent on an input signal received at the input terminal. A polarity detector is coupled in parallel with the load path of the first transistor device. The polarity detector includes a second transistor device and a current detector. The second transistor device includes a load path connected to the load path of the first transistor device. The current detector includes a sense path in series with the load path of the second transistor device and an output connected to the input terminal of the drive circuit.
