Abstract

Provided are a motor driving circuit, a control method therefor, and a driving chip. The motor driving circuit includes a logic module and a push-pull module, a channel selection module, an instruction recognition module, and an isolating switch module. An input signal is outputted by the logic module and the push-pull module to control the motor. The channel selection module is 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 configured to perform a corresponding operation on the isolating switch module according to an inputted instruction. The isolating switch module is 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.
