A drive circuit includes a first transistor coupled in series with a second transistor at a first intermediate node coupled to a load. An amplifier has an output driving a control terminal of the second transistor. The amplifier includes a first input coupled to a second intermediate node and a second input coupled to a reference voltage. A feedback circuit is coupled between the first intermediate node and the second intermediate node. A slope control circuit is coupled the second intermediate node. The slope control circuit injects a selected value of current into the second intermediate node, that current operating to control the output of the amplifier in setting a slope for change in voltage at the first intermediate node.
