摘要： A method of state maintenance for a MMC system. The method includes using a plurality of signals, including a working voltage signal, a low voltage detection (LVD) signal, an LVD interrupt signal, a firmware polling signal, an LVD interrupt reset signal. The LVD signal responds to a voltage level of the working voltage at a preset voltage level. The LVD interrupt signal responds to the level of the LVD signal. After the LVD signal returns to the high level state and the firmware polling signal does the polling action to the LVD interrupt signal, then the LVD interrupt reset signal is issued to reset the LVD interrupt signal.

摘要翻译： 一种MMC系统的状态维护方法。 该方法包括使用多个信号，包括工作电压信号，低电压检测（LVD）信号，LVD中断信号，固件轮询信号，LVD中断复位信号。 LVD信号以预设电压电平响应工作电压的电压电平。 LVD中断信号响应LVD信号的电平。 在LVD信号返回到高电平状态并且固件轮询信号对LVD中断信号进行轮询动作之后，发出LVD中断复位信号以复位LVD中断信号。

摘要： A battery management system includes an external non-volatile memory and a battery management chip with embedded SRAM, CPU, ROM, and ROM_RAM encoder. The chip communicates with the non-volatile memory via standard protocols. While the battery management system is powered on or reset, a battery management program stored in the non-volatile memory is loaded to the embedded SRAM and the executed by CPU. As turning off this system, the program in the SRAM is then restored back the non-volatile memory. A battery protection IC is optionally embedded in the chip or externally connected with this chip to protect the battery from over-/under-voltage, over-current and short-circuit in both charge and discharge.
