An electronic control system provides selectable path operation, such as linear and pulse-width modulated (PWM) operation and provides path transition management to improve operation. The system supplies a current or a voltage to a load in response to an input signal or value and includes an output driver, and multiple selectable control paths. The system includes a control circuit that selects between the first control path and the second control path in response to a path selection indication to drive the output driver. The system may include an evaluator that determines the path selection indication in conformity with an amplitude and a slew rate of the input. One or all of the control paths may have a response time to changes in the input signal or value, and the control circuit may delay switching from the second control path to the first control path to compensate for the response time.
