Hi TI Team,
I refer to the design of BQ25570 EVM and my schematic is as follows.
I am applying 2.8V to VIN. I get 3.9V in VSTORE and only 1.2V in VBAT. And the waveform of VBAT looks like the figure below.
Is there anything wrong in my schematic? I am sure my soldering is correct. How can I solve it?
Thank you so much!
