摘要： This disclosure is directed to techniques that may accurately determine the amount of current flowing through a power switch circuit by measuring the voltage across the inherent impedance of the circuit connections. One connection may include a low impedance connection between the power switch output and ground, where the low impedance connection may be on the order of milliohms. By using a four-wire measurement, the sensing connections are not in the current path, so the measured value may not be affected by the current. The connection that makes up the current path can be accomplished with a variety of conductive materials. Conductive materials may have a temperature coefficient of resistivity that may impact a measurement of electric current as the temperature changes. Measuring the temperature of the current path, along with the voltage across the connection, may allow a more accurate current measurement.

摘要： A semiconductor arrangement may comprise a multiplicity of semiconductor elements with controlling paths and controlled paths, the controlled paths having controllable conductivities and being connected parallel to each other. The semiconductor arrangement may also comprise a current evaluation circuit configured to measure current strengths of currents present in the controlled paths and to provide a signal representing the sum of the measured current strengths, and a control circuit connected to the controlling paths and configured to control the conductivities of the controlled paths in accordance with an input signal and the signal representing the sum of the current strengths, wherein at least one controlled path is controlled to have minimum conductivity if the signal representing the sum of the current strengths is below a threshold value.
