I am trying to test the BQ24022 charging IC and checking the operation flow chart I am quite certain that the requirements have all been met for the IC to begin charging from a USB input but I am not seeing a rise on the STAT1/2 pins. Sometimes I see a very small ~0.1V rise but that is it.
Is it necessary to place pull-ups on these lines? Is there anything else that could be causing this problem?
Thanks
