BQ25895M: Why is the instantaneous current to 70-80ma when the main chip reads the battery value of BQ25895M?

Part Number: BQ25895M

Hi TI experts,

We currently have a mouse project using BQ25895M. When the main chip reads the register of BQ25895M to obtain the battery voltage, the instantaneous current will reach 70-80ma, while the normal working current of the mouse is about 4mA

Hi,

What are the test conditions such as VBUS, VBAT, IBAT, VSYS, ISYS when the behavior happens?

Thanks,

Ning.
