CURRENT SENSING METHODS AND APPARATUS IN AN APPLIANCE |
摘要 |
A motor control circuit includes a first winding switch, a first switch driver circuit, and a current sense circuit. The first winding switch has a control input and is operable to activate a first motor winding. The first switch driver circuit is coupled to the control input. The current sense circuit is operably coupled to a second winding. The current sense circuit includes a sense resistor, the sense resistor comprising an etched trace in a printed circuit board. The etched trace has a geometry defining a resistance of the sense resistor.
