In the datasheet, Pin Functions table (section 7, page 5), STAT pin says "Open-drain charge status pin with 10-kΩ pullup to power rail."
Is there an internal pullup?
If so, to which power rail?
Section 9.2 Functional Block Diagram shows no internal pullup.
I wish to connect STAT pin to an MCU with 3.3V I/O, configuring this I/O as input with pullup (to the MCU's 3.3V). I want to make sure there isn't another pullup to a higher voltage rail that might stress the MCU input.
