| description | The invention provides an isolation type CAN wake-up circuit. The isolation type CAN wake-up circuit comprises a CAN chip, a first isolation circuit, a second isolation circuit and an interference suppression circuit, wherein the first isolation circuit, the second isolation circuit and the interference suppression circuit are connected with the CAN chip; the connection of pins on the CAN chip comprises the following steps: a TXD pin is connected with an MCU through the first isolation circuit, an RXD pin is connected with the MCU through the second isolation circuit, a CANH pin and a CANL pin are connected with a CAN bus through the interference suppression circuit, a VBAT pin and a WAKE pin are connected with a wake-up trigger signal, and an INH pin is connected with a power supply of the MCU; and if the MCU needs to be awakened, a VBAT pin and a WAKE pin of the CAN chip receive an awakening trigger signal, act on an INH pin and generate an awakening signal to awaken the power supply of the MCU.
