My customer asked the pre-charger Current of bq24616. In the file "bq246xx Device Comparison", it is stated that the minimum adjustment is 125mA through R. How is this minimum calculated? Can it be adjusted to the minimum and not more than 100mA?

Hi Hsu,
See this link where the question has been aswered: https://e2e.ti.com/support/power-management/f/196/t/568582?tisearch=e2e-sitesearch&keymatch=minimum%252525252520precharge
You can also increase sense resistor, as precharge current is dependent on both VISET2 and value of RSR. Minimum precharge current for 10mohm resistor is clamped at 125mA.
