What is the condition on your BAT pin? Did you connect a 3.5V battery?
Can you send me the waveform at BAT pin?
After connecting the battery to the Vbatt terminal the battery is not charging. It is detected as the charging and Pgood led's glow's on . After removing the battery if I check the terminal it shows 0.645 V.
When i try in the other mode i.e Taking TD pin high the Vbatt is 0.648V
I already have EVM for BQ24072 .
please mail me your email id so that i can show you my CAD files .
