Abstract
An integrated circuit device for controlling and sensing electrical current is provided. The integrated circuit device comprises a main transistor device, configured for controlling a main current, and a plurality of sensing transistor devices, configured for controlling a combined sensing current. The main transistor device and the plurality of sensing transistor devices are connected to a common gate node. The on-state resistance of the main transistor device is lower than a combined on-state resistance of the plurality of sensing transistor devices. The sensing transistor devices are distributed throughout at least a section of the integrated circuit to reduce an influence of at least one local property of the integrated circuit device on the combined sensing current.
