Hi, Team

My customer is studying BQ51050B for 4.2V battery.

But the charge current only 50mA~150mA, does the BQ51050B could support this small charge current?

The bq5105X is not accurate at measuring low currents needed for termination at small charge currents.
Device would not be a good fit here.
Also see TIDA-00318.
