I am in need of your advice on a BMS design. I am designing a circuit which gets powers from battery or USB input (with Power Path management). After searching I found BQ24232 IC (http://www.ti.com/lit/ds/symlink/bq24232.pdf) will work for me.
Here, I need to have an LED to indicate charging complete (Battery Full). The IC has a ~CHG pin which goes to VSS while charging and get high impedance when getting full, according to the datasheet.
As the datasheet is only giving words on using it to indicate charging status,by connecting LED between output and this pin, I would like to know if this will work if I connect LED between this pin and VSS to indicate battery-full status. I will appreciate every single possible advice from you all.
Edit: In summary, I need to understand what does this mean by "~CHG is high impedance when charging is complete". And how can I make use of this pin for Battery-full indicator LED?
