Abstract
A technique for operating a driver includes enabling the driver to provide a first current through a first terminal of a driver device of the driver in a first mode of operation. The method includes sensing a voltage drop across the first terminal and a second terminal of the driver device to generate a sensed voltage level indicative of the voltage drop. The method includes generating a comparison output signal indicative of a comparison of the sensed voltage level to a threshold voltage level. The method includes selectively enabling the driver to provide a second current in a second mode of operation based on the comparison output signal. The first current may be less than the second current. The enabling may include enabling a first portion of the driver device using a first control signal, while a second portion of the driver device is disabled using a second control signal.
