I am planning on using a Diodes Inc. AP9211 battery protection circuit for an IoT project, and I have a question regarding usage.
The AP9211 will be embedded in the PCB, while the battery will be inserted afterwards. Once the battery is inserted, I do not expect to change it long-term. My schematic for the battery protection follows the datasheet guidelines, except I connect P- (the PACK- shown in the datasheet) to GND directly, as this is the GND of the whole circuit.
Since this IC is intented to be used in the battery pack and not separate, do you see any issues with connecting P- directly to GND? I would think not, because even if I placed the AP9211 on the battery pack, I would then connect P- to my circuit's GND through a cable or connector of some sort.
