Abstract

The present invention provides improved slew rate control over a varied operating temperature range. A switching device (P1, N1) receives from a predrive circuit (56) a control signal that limits a slew rate of the switching device's output and also varies proportionally to the operating temperature. In this manner, the effect of temperature on the slew rate can be reduced.
