1. A motor driving circuit, comprising a logic module and a push-pull module, a channel selection module, an instruction recognition module, and an isolating switch module, wherein:
an input signal is outputted by the logic module and the push-pull module to control the motor;
the channel selection module is connected to the isolating switch module and the instruction recognition module, respectively, and configured to select a channel for the input signal to make the input signal to be connected to the isolating switch module or the instruction recognition module, or disconnected;
the instruction recognition module is connected to the channel selection module and the isolating switch module, respectively, and configured to perform a corresponding operation on the isolating switch module according to an inputted instruction; and
the isolating switch module is connected to the channel selection module, the instruction recognition module, and the logic module, respectively, and configured to receive an instruction of the channel selection module and an instruction of the instruction recognition module to connect or disconnect the logic module.
