An active pull-up system for use with a motor is described. The active pull-up system comprises: a first resistor coupled to an output node; a first switch and a second resistor coupled in parallel with the first resistor, wherein the first switch is in series with the second resistor; a latch coupled to the first switch for either keeping the first switch open or closing the first switch in response to receiving a closing signal; and a threshold comparator coupled between the output node and the latch, wherein the threshold comparator transmits the closing signal when the output node exceeds a threshold value, which actively pulls up the output node.
