监集成电路监控电池供电设备

资料介绍
大多数基于微处理器的系统,以确保正确的操作,需要在上电和掉电的监督,并在进入或退出关机或休眠模式。主管可能只提供了一个上电复位,或它可以提供额外的功能,如备份电池管理,存储器写保护,低线的预警,或软件看门狗(图1) 。

APPLICATION NOTE 655
Supervisor ICs Monitor Battery-Powered Equipment


To ensure correct operation, most microprocessor-based systems require supervision during power-up and power-down, and when entering or exiting
shutdown or sleep mode. The supervisor may only provide a power-on reset, or it may offer additional functions, such as backup-battery management,
memory-write protection, low-line early warning, or a software watchdog (Figure 1).
