Motor drive circuit, control method and drive chip
The invention discloses a motor drive circuit, a control method and a drive chip. The motor drive circuit comprises a logic module and a push-pull module. An input signal is output through the logic module and the push-pull module to control a motor. The motor drive circuit further comprises a channel selection module, a command recognition module and an isolation on-off module. The channel selection module carries out channel selection on the input signal and selectively communicates with the isolation on-off module or the command recognition module or suspends. The command recognition moduleexecutes corresponding operation to the isolation on-off module according to the input command. The isolation on-off module receives commands of the channel selection module and the command recognition module and communicates or disconnects with the logic module. Through the arrangement of the channel selection module and the isolation on-off module, dual-layer isolation is formed, the antijamming capability of the drive circuit is enhanced, the influence of Tesla coils on a door lock device is avoided, circuit reliability is improved, safety is high, and the number of GPIOs in communicationwith a controller is reduced.
本发明公开了一种电机驱动电路、控制方法、驱动芯片，包括逻辑模块、推挽模块，输入信号经逻辑模块、推挽模块输出，对电机进行控制，还包括通道选择模块、指令识别模块、隔离开关模块，所述通道选择模块对输入信号进行通道选择，选择联通隔离开关模块或指令识别模块或悬空；指令识别模块根据输入的指令对隔离开关模块执行相应的操作；隔离开关模块接收通道选择模块、指令识别模块的指令，连通或断开逻辑模块，本发明通过设置通道选择模块、隔离开关模块形成双层隔离，加强了驱动电路的抗干扰能力，避免了特拉斯线圈对门锁装置的影响，提高电路可靠性，安全性高，也减少了与控制器通信GPIO个数。
