<p>The integrated circuit (10) includes a power driving device (12) and a pilot device (14) for sensing current through the powder driving device (12). 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 (12) 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 (16) activates the secondary pilot.</p> |
