HI
I'm trying to use lpcom to detect when the battery voltage is dropping.
The configuration is as follows: 5V battery voltage output is reduced to 3.0V through LDO and supplied to nRF52832.
* Battery voltage = 5.0V --- > LDO output = 3.0V -----> nRF52832
* The battery voltage is divided by a resistance of approximately 2M or more and input to the lpcom port.
There were no problems with the basic implementation in operation tests and continuous tests for about a month.
But when I looked again,
When the battery is fully charged... the VDD voltage of nRF52 is set high by about 0.9V.
Could this part be a problem?
There is no problem in operation, but will there be a problem in the long run if a voltage higher than the guaranteed voltage is applied?
