My project uses Li-ion battery charger LTC4099 (https://www.analog.com/media/en/technical-documentation/data-sheets/4099fd.pdf). And S6E2DH FM4 microcontroller (https://www.cypress.com/file/224786/download). I want to detect the presence of the ouput voltage VOUT of the charging controller (in the attached picture) using the microcontroller. What are some sensible ways to do it? Please let me know. Thanks.
PS: I want to measure using a voltage divider but dont exactly get it because the VOUT of the battery charge controller is varying but not always constant. Isn't it?
