ABSTRACT:
A circuit for sensing the current through a power MOSFET in both the linear and saturated regions of operation of the power MOSFET comprising a first circuit coupled to the power MOSFET for sensing the current through the power MOSFET in the saturated region of operation of the power MOSFET and a second circuit coupled to the power MOSFET for sensing the current through the MOSFET in the MOSFET's linear region of operation.
