Abstract
The integrated circuit includes a power driving device, and a pilot device for sensing current through the power driving device. The pilot device includes a composite pilot having a plurality of series connected transistors and which is at least active while the power driving device is in a linear mode, and a secondary pilot which is active while the power driving device is in a saturation mode. Also, a control circuit activates the secondary pilot.
