Hello.
I'm writing a Linux driver for the bq24190 but I still have a few questions. They are:
1) How can I tell if there is a battery attached? This is useful to know for reporting userspace and also since the "BATFET Turn Off" section recommends turning off BATFET when there is no battery attached.
2) When in host mode with REG02[0] set (20%), the "Terminatoin when REG02[0] = 1" section says that the termination function should be disabled and the host should disable charging when the battery is fully charged. How can the driver tell when the battery is fully charged?
3) In the section labelled, "Charging Safety Timer", paragraphs 2 & 3, what happens when the safety timer expires when in default mode is pretty much the opposite of what happens when it expired in host mode. Are those paragraphs correct??
Thanks,
Mark
