Hi,
I have the following circuit. VSYS from buck is ok, VCC is 4.5V, the battery is a lipo at half charge and has its NTC. But there is 0A flowing from the IC to the battery. What am I doing wrong?
Thanks!
Hello Sebastian, welcome to the MPS Forums.
I want to ask a question just to narrow down what the issue could possibly be. Does the LiPo battery stop charging at half the capacity in this case or just doesn’t charge at all? If so, you might want to check the Vbatt threshold limit and increase it. What is the full charge voltage of your LiPo battery? I am assuming 4.2V but just wanted to double check.
Also, I wanted to point out that the MP2625 is not recommended for new designs. Your schematic shows that you have the MP2625B, which is a perfectly functional IC. Just wanted to make sure you have the right IC as well.
Hope to hear back from you soon,
Krishan
