The invention discloses a power-on and power-off method for a function-integrated motor controller. The method comprises the steps of S1 enabling a power supply conversion chip to jump from a first state to a second state when receiving a wake-up signal outputted by a wake-up circuit and judging that the wake-up signal is valid, and enabling the power supply conversion chip to output a voltage, so as to enable the power-on initialization of a single-chip microcomputer, and enable the power supply conversion chip to jump from the second state to a third state. The power-on and power-off method for the function-integrated motor controller has the advantages of being simple in hardware topology, flexible in function, low in cost and the like, a hardware basis is provided for a flexible power-on and power-off control scheme of the multifunctional motor controller, a power-on and power-off circuit is simplified on the basis that existing functions are not affected, the potential failure hidden danger caused by hardware reset is avoided, and various wake-up signals can be flexibly integrated.
本发明公开了一种功能集成式电机控制器的上下电方法,包括步骤S1:供电电源转换芯片接收到唤醒电路输出的唤醒信号并且判断唤醒信号有效时,由第一状态跳转到第二状态,并且供电电源转换芯片输出电压,以使得单片机上电初始化,供电电源转换芯片从第二状态跳转到第三状态。本发明公开的一种功能集成式电机控制器的上下电方法,其具有硬件拓扑简单、功能灵活和成本低等优点,为多功能电机控制器灵活的上下电控制方案提供硬件基础,在不影响现有功能基础上,简化了上下电电路,不仅避免了硬件复位带来的潜在失效隐患,还可以灵活的集成了多种唤醒信号。
