Power-on and power-off method of function integrated motor controller

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 har
