ABSTRACT:
A motor driving circuit comprising first and second input voltage source sets, a reference voltage source, first and second voltage level shift units, a logic unit, and an output voltage terminal. The first input voltage source set provides a first input voltage set. The second input voltage source set provides a second input voltage set. The reference voltage source provides a reference voltage. The first voltage level shift unit raises part of levels of the first input voltage set to a level of the reference voltage. The second voltage level shift unit partially raises levels of the second input voltage set to a level of the reference voltage. The logic unit receives the reference voltage and the first input voltage set and outputs a control voltage. The output voltage terminal receives the control voltage and outputs an output voltage.
