Abstract
A system, in some embodiments, comprises: a motor; and control logic, coupled to the motor, to determine a duty keep status and a duty cycle threshold based on a received voltage, wherein the duty keep status indicates whether the system is to operate in a duty keep mode or a stop mode, wherein the duty cycle threshold indicates a minimum duty cycle for the motor if the system operates in said duty keep mode and indicates an input duty cycle threshold below which the control logic shuts off the motor if the system operates in the stop mode.
