Other Parts Discussed in Thread: TPS65994BG, BQ25758
Hi,
We have apply PD3.1 EVM set(TPS65994BG+TPS26630+BQ25758), when we test on some ACER notebook(Swift3).
The notebook ask for 20V/3.25A power, the TPS65994BG source ability is 20V/5A.
But seems TPS65994BG only set output curremt protection at 20V/3.25A even it can support to 20V/5A, it caused when notebook is low battery condtion, it may drain over 20V/3.25A,
And let trigger OCP protection and auto retry.
Is it possibl to set TPS65994BG to maximum 20V/5A output even when the sink side only declare 20V/3.25A?
It will avoid this OCP cause connection retry in some condition.
Below is log for you reference. It can open with GRL tool.
