Abstract
A positive hysteresis elimination comparison circuit and a motor driver having a positive hysteresis elimination comparison circuit are provided. The motor driver includes a comparator and a hysteresis switching circuit. The comparator compares a voltage of a first voltage signal received by a first input terminal of the comparator with a voltage of a second voltage signal received by a second input terminal of the comparator to output a comparing signal within a comparison time. When the voltage of the first voltage signal is lower than the voltage of the second voltage signal, the comparison time is delayed. When the voltage of the first voltage signal is higher than the voltage of the second voltage signal and a positive hysteresis elimination signal is received by a first control terminal of the comparator, the comparison time is not delayed.
