Abstract
The present invention provides a new limiting signal circuit configuration for the connection of a pulse-width modulation motor controller integrated circuit. This new circuit allows for increased control over the over-current protection scheme while increasing the maximum available current levels. The invention utilizes a resistor based voltage divider connected to an input power source to provide a sliding scale current limiting signal in proportion to the input voltage. This method provides protection in relationship to the incoming power signal.
