Zusammenfassung:A message pulse signal wake-up circuit, method, chip and in-vehicle infotainment wherein the message pulse signal wake-up circuit comprises: a signal input module for receiving a message pulse signal sent by at least one transceiver and sending the message pulse signal to a delay module; the delay module is connected between the signal input module and the signal output module and is used for delaying the message pulse signal and sending the message pulse signal to the signal output module; and the signal output module is used for generating a level awakening signal from the delayed message pulse signal and awakening the chip to be awakened. Therefore, the message pulse signal output by the transceiver with the cost advantage can be converted into the level wake-up signal, the trigger wake-up of the processor or equipment only supporting the receiving level signal wake-up is realized, and the cost is effectively reduced. In addition, the circuit also supports multi-path message wake-up, the flexibility and ap
