From MP2722 datasheet:
The IB output voltage is between 0V and VCC. The host can measure the IB voltage to make a software fuel gauge or monitor the peak discharge current.
What does the IB voltage indicate?
Hi @c.tan,
Please see below:
It provides the battery current information. More detailed information can be found on Pg. 22 of the DS.
Thank you
