Hello,
I was interfacing MAX17330 using an MCU.
1. Connected 850mAh battery to BATTP and BATTN and configured accordingly.
2. Enabled parallel battery management.
3. Connected 5V supply at SYSP and SYSN.
Looking at the datasheet, in Figure 6. Charging and Discharging States, there are few ways to know charger source is present or not.
1. (VPCKP – VBATT)*> + 30mV
2. AvgCurrent* > +1.4mA
3. Current* > +7.5mA
4. (VCSP-VCSN) > +180mA
I understand that when parallel charging is enabled, i have to clear the AllowChgB bit in status register within 1.4sec. I did that and the battery was charging. But now i wanted to get an alert that the charger is connected so that i can start the process. I could not find any alert for PCKP register and wanted to know if this is possible or not, or any other way to know the charger is connected?
Further if i disable the parallel charge, I do not get the option to Allow Charge option which is valid because it falls under parallel charge management. But what if i am having a single battery and i just want to charge that battery. How to enable the charger?
Any assistance will be appreciated.
Regards
P.S I have attached the screen shot where only one battery is connected with one MAX17330 and parallel charge is disabled. Here i am not able to start the charging process of the battery.
