Hi.
How negative was the output?
Are you using the evaluation board for this IC?
If possible please send us your schematic so we can evaluate further.
For the meantime, I recommend that you check the setting of the MODE pin first.

Thank you .However,I have a other question.When the charging and discharging current of lithium battery is higher than 10A, why does the output voltage fluctuate and the SS pin of ADP1972 also change?
Hi.
Thank you for your question. Unfortunately, we can only provide support to amplifier-related questions in this particular community.
Kindly address your question to the "Power by Linear" community in this link: https://ez.analog.com/power
Thank you very much,

Hi.
I'm sorry but can you still send us your schematic so we can evaluate your question better? I would like to know how AD8540 and ADP1972 are connected in your circuit.
Thank you very much,

你好,AD8450补偿设计工具怎么找,链接打开没有找到,能更加具体点吗?
Thank you.Why AD8450 compensation design tools, when using the software does not reflect?And Iknow
