Abstract
An apparatus includes a controller that measures a first voltage across a first circuit path including a series connection of a first switch and a shunt resistor. The first voltage generated based on first current supplied from a first winding of a motor including multiple windings. Based on the magnitude of the first voltage, the controller determines an ON-resistance of the first switch. The ON-resistance can be used final office action any suitable purpose. For example, the controller can be configured to use the determined ON-resistance of the first switch to controller operation of a motor including the first winding. For example, the determined ON-resistance can be used as a basis to determine an amount of current through first switch and corresponding first winding of the motor.
