Circuit for driving transistor e.g. MOSFET, has actuation current source which is provided to receive measurement signal, and provide actuation current having a current level dependent on measurement signal at actuation output

摘要

The circuit has an input to receive an input signal, and an actuation output (31) that is to be connected to an actuation terminal of a transistor (1). A measurement arrangement ascertains a load current through a load path of transistor and a load voltage across load path of transistor, and provides a measurement signal that is dependent on load currents and load path voltages. An actuation current source (7) receives measurement signal, and provides an actuation current having a current level dependent on measurement signal at actuation output.
