| Zusammenfassung: | Disclosed is a motor driving circuit which includes a first input voltage source group which is used to provides the first input voltage source group, a second input voltage source group which is used to provides the second input voltage source group, a reference voltage source which is used to provides a reference voltage, a first voltage level shift unit which is used to increase the level of the first input voltage source group to the level of the reference voltage, a second voltage level shift unit which is used to increase the level of the second input voltage source group to the level of the reference voltage, an operation unit which is used to receive the reference voltage and the first input voltage source and to selectively output a control voltage, and a voltage output terminal which is used to receive the control voltage and to output an output voltage. The motor driving circuit of the invention avoids the current leakage and level instability when the circuit is electrified. |
