A segmented driver including at least one drive pin and a sense pin, a driver circuit, a comparator, and a controller. The driver circuit activates a selected drive level between the drive pins and a reference node. The comparator compares a voltage of the sense pin with a threshold voltage and provides a threshold indication when the voltage of the sense pin reaches the threshold voltage. The controller commands the driver circuit to activate a first drive level in response to an off indication, and commands the driver circuit to switch to a second, lower drive level in response to the threshold indication. The driver circuit may be implemented using low resistive current devices. Multiple drive pins may be included, each for selectively activating a corresponding drive path to adjust drive level. The threshold voltage may be set using a current source and resistor, and may be adjusted for temperature.
