The invention discloses a power management integrated circuit, a micro-control unit and a vehicle body central controller, the vehicle body central controller comprises the power management integrated circuit and the micro-control unit, the power management integrated circuit is connected with the micro-control unit, and the power management integrated circuit is used for performing voltage conversion on a whole vehicle power supply voltage to obtain a target voltage; and when it is determined that the power supply voltage of the whole vehicle is normal, a state switching signal is sent to the micro-control unit in response to a dog feeding signal sent by the micro-control unit, and the state switching signal is used for indicating the micro-control unit to be switched from a standby mode to a normal mode. In this way, after the micro-control unit is powered on based on the target voltage, the state switching signal can be sent to the micro-control unit to indicate the micro-control unit to be switched from the standby mode to the normal working mode, so that the micro-control unit is awakened, the micro-control unit in the normal working mode can normally power on the whole vehicle, and the service life of the whole vehicle is prolonged. And normal operation of the whole vehicle is maintained.

    本申请公开了一种电源管理集成电路、微控制单元和车身中央控制器,车身中央控制器包括电源管理集成电路与微控制单元,电源管理集成电路与微控制单元连接,电源管理集成电路用于对整车供电电压进行电压转换得到目标电压,并基于目标电压为微控制单元供电,在确定整车供电电压正常时,响应于来自微控制单元发出的喂狗信号,向微控制单元发送状态切换信号,状态切换信号用于指示微控制单元从待机模式切换至正常模式,这样在基于目标电压为微控制单元供电之后,可以通过向微控制单元发送状态切换信号,指示微控制单元从待机模式切换至正常工作模式,实现了微控制单元的唤醒,以使正常工作模式的微控制单元可以为整车正常上电,维持整车的正常运行。
