The invention relates to an automobile area controller, a dormancy wake-up circuit and method thereof and an automobile, the automobile area controller comprises wake-up sources, a diode array, a high-side driving chip, a power supply chip, a shallow dormancy power supply and an MCU, and the wake-up sources comprise at least one main wake-up source and one secondary wake-up source; the input end of the high-side driving chip is connected with a vehicle-mounted power supply, the enabling end of the high-side driving chip is connected with the output end of the diode array, and the output end of the high-side driving chip is connected with the input ends of the shallow dormancy power supply and the power supply chip; the output end of the power supply chip is connected with a power supply input pin of the MCU so as to provide a working power supply for the MCU when the high-side driving chip is switched on; the main wake-up source is connected to the enabling end of the high-side driving chip after being combined through the diode array, and is connected to the wake-up end of the MCU at the same time; and the secondary wake-up source is directly connected to the wake-up end of the MCU. The problem that the quiescent current of an existing automobile area controller in a sleep mode is large is solved.
本发明涉及一种汽车区域控制器、其休眠唤醒电路、方法及汽车,包括唤醒源、二极管阵列、高边驱动芯片、电源芯片、浅休眠电源和MCU,其中:唤醒源包括至少一个主要唤醒源和一个次要唤醒源;高边驱动芯片的输入端与车载电源连接,高边驱动芯片的使能端与二极管阵列的输出端连接,高边驱动芯片的输出端分别与浅休眠电源、电源芯片的输入端连接;电源芯片的输出端与MCU的电源输入脚连接,以在高边驱动芯片导通时为MCU提供工作电源;主要唤醒源通过二极管阵列合路后接入高边驱动芯片的使能端,并同时接入MCU的唤醒端;次要唤醒源直接接入MCU的唤醒端。本发明解决了现有汽车区域控制器在休眠模式下的静态电流较大的问题。
