I started reading bq24032A's datasheet and found a parameter called Vi(OUT). I still got no luck finding out what it stands for after a few time looking around. Regarding to literal meaning, I guess it is the voltage reading on OUT pin. The Vi(OUT) parameter also appear on Figure 3. Charge Control Operational Flow Chart(deciding whether go to sleep mode or not). So I believe the term Vi(OUT) should appear also on FUNCTIONAL BLOCK DIAGRAM, but I found nothing. I am wondering what is Vi(OUT) actualy mean...
