Hi Team,
Some question about BQ24780S:
1. The application is using removable battery, and we connect /BATPRES to GND. Does this has any side effect?
2. Now /BATPRES is connecting to GND, what if now remove battery?
3. In reference design, the pull high voltage 3.3V is supply from external power. The question is, the sequence of 3.3V is after SYSTEM power on, so before ACFET turns on, the SMBUS and ILIMIT can not get the pull high voltage, does this affect charger operation?
4. Follow question3, or I need a LDO supply 3.3V from AC adapter input?
5. If I use REGN as ILIM's reference voltage, then any side effect?
6. If I use REGN as SMBUS's reference voltage, then any side effect?
Thank you very much,
C.T.
