Abstract
A circuit having a power transistor and drive circuit is disclosed. One embodiment provides a drive terminal and a load path. The power transistor is integrated in a first semiconductor body. A first sensor arrangement having a sensor transistor is integrated in the first semiconductor body. The sensor arrangement provides a first sensor signal dependent on a threshold voltage of the sensor transistor. A drive circuit to which the first sensor signal is supplied and designed to drive the power transistor via its drive terminal as a function of the first sensor signal.
