Abstract

An apparatus includes a controller that controls operation of an amplifier. The amplifier receives a sample voltage produced by a resistive path; the sample voltage from the resistive path is indicative of a magnitude of current through a motor winding. The controller selects a gain setting to apply to the amplifier based on one or more conditions. The selected gain setting is selected amongst multiple possible gain settings. Subsequent to selection, via application of the selected gain setting to the amplifier, and based on an output of the amplifier, the controller monitors a magnitude of the current through the motor winding. According to one configuration, the amplifier adjusts the magnitude of the selected gain setting depending on one or more parameters such as the magnitude of the current through the motor winding, a selected operational range of controlling current through the motor winding, etc.
