My design contains LTC4060 for charging 2 cells.
Outputs CHRG\ and ACP\ are linked to pulled up GPIO of the MCU.
I wander in which state the outputs CHRG\ and ACP\ (open drain) are when the LTC4060 is not powered.
Is there a risk the LTC4060 be powerd by the pull up resistors?
The /CHRG and /ACP pins are high-Z when the LTC4060 is not powered. Applying voltage to them (like through the pull-ups as you mentioned) will not power the part.
Thanks for your feedback.
After tested it, I confirm it.
