输入电压是指VCC的电压吗?这个电压要保证高于5V。
PG管脚:Open-drain power-good status output. The transistor turns on when a valid VCC is detected. It is turned off in the
sleep mode. PG can be used to drive an LED or communicate with a host processor. It can be used to drive ACFET
and BATFET.
另外 所用的电路和器件是和datasheet里面的一致的吗?
是VCC,请您再确认一下,是所有的电容都用陶瓷的吗,我觉得现在是电池检测和RSN RSP端的问题
1,文档22页Vrech和Vlowv究竟是多少,他们指的是Vfb脚电压还是电池电压
2, 我的14 15脚输出的是直流5.6v,没有波形,有没有相应的解释
3,预充阶段stat led 应该是什么状态,长亮?
