摘要：
A power device can be structured with a power switch having multiple arrangements such that the power switch can operate as a power switch with the capability to measure properties of the power switch. An example power device can comprise a main arrangement of transistor cells and a sensor arrangement of sensor transistor cells. The main arrangement can be structured to operate as a power switch, with the transistor cells of the main arrangement having control nodes connected in parallel to receive a common control signal. The sensor arrangement of sensor transistor cells can be structured to measure one or more parameters of the main arrangement, with the sensor transistor cells having sensor control nodes connected in parallel to receive a common sensor control signal. The sensor transistor cells can have a common transistor terminal shared with a common transistor terminal of the transistor cells of the main arrangement.
