Patent ID: 7126354

Claim:
A circuit configuration, comprising: a load transistor having a first and a second load path terminal and a control terminal; and a current measuring configuration for ascertaining a load current through said load transistor and including: a first current sensor with a first current measuring transistor having a first and a second load path terminal and a control terminal, said first load path terminal being connected to said load path terminal of said load transistor and said control terminal being connected to said control terminal of said load transistor, and said first current sensor providing a first current measurement signal; a second current sensor with a second current measuring transistor having a first and a second load path terminal and a control terminal, said first load path terminal being connected to said first load path terminal of said load transistor and said control terminal being connected to said control terminal of said load transistor, and said second current sensor providing a second current measurement signal; and an evaluation circuit connected to said first and said second current sensors, receiving the first and the second current measurement signals, and providing a current measurement signal depending on the load current.
