Hi Team,

What is the input current limit for BQ25710 and BQ25720.Which means what is the maximum current supported from 19V AC/DC adapter.
From BQ25720 reference notebook design i come to know it can support 140W .Likewise i need data for BQ25710.

Hi Saravanan,

See below post on the current sense. You can use BQ25710 for 140W power. BQ25720 has slightly better efficiency through.
