Component arrangement having a transistor and an open-load detector

摘要

One embodiment of the invention relates to a component arrangement including a load and an open-load detector. The load transistor has a first transistor region arranged in a semiconductor body, a second transistor region arranged in the semiconductor body and a third transistor region arranged between the first transistor region and the second transistor region and doped in complementary fashion to the first transistor region and the second transistor region. The open-load detector has a sense region arranged in the third transistor region and of conduction type complementary to the third transistor region and having an evaluation circuit connected to the sense region.
