你好,
在第130页的PSoC63的TRM中,我读到以下内容:
-在Hibernate模式中不可用BLONDOUT检测(BOD)块。结果,该设备不会在休眠模式中从闪避事件恢复。不进入冬眠,需要掉电检测,即应用模式,应用在供应不稳定。
在我们的应用程序不能保证一个稳定的
电源,所以它是可能的,电压低于BOD电压然后再上升。因为它是一个低功率的应用,我们必须使用休眠模式。
问题:如果设备在休眠模式和电压低于BOD和再次升起,会发生什么?将芯片卡住,无法恢复/重新启动吗?要添加一个外部的超级用户IC RESET引脚,唯一的解决办法吗?
谢谢您!
当做

Hello,
in the TRM of the PSoC63 on page 130 I read the following:
- The brownout detect (BOD) block is not available in Hibernate mode. As a result, the device does not recover from a brownout event in Hibernate mode. Do not enter Hibernate mode in applica
tions that require brownout detection, that is, applications where the supply is not stable.
In our application we can not guarantee a stable power source, so it is possible that the voltage drops below the the BOD voltage and then ramps up again. As it is a low power application, we must use the Hibernate mode.
Question: What could happen if the device is in Hibernate mode and the voltage drops below BOD and rises again? Could the chip get stuck and does not recover / reboot itself? Is the only solution to add an external super visor IC to the reset pin?
Thank you!
