Abstract
A system, in some embodiments, comprises: an analog-to-digital converter (ADC) configured to receive a discrete analog voltage and to generate a digital bit value representing said analog voltage; control logic, coupled to the ADC, configured to identify a target intercept and a target slope for a lead angle curve based on the digital bit value; and a motor, coupled to the control logic, configured to operate based on a lead angle identified using said lead angle curve, wherein the ADC receives the analog voltage via a single integrated circuit pin.
