BQ24295 charger: input current limit is reset

Other Parts Discussed in Thread: BQ24295

About the TI BQ24295 charger of our product with the AC adapter,

we met an issue after BQ24295 is forced to 5V/2A as follows:

>>  BQ24295 will run input current detection and update input current limit in REG00[2:0] automatically.

>>  The result is “USB host” and the input current limit is reset to 500mA.

 

   1) The Chapter 8.3.1.4.3 of the datasheet for BQ24295

 

   

   1-1) And after the input current limit detection is done, the input current limit is updated in REG00[2:0].

 

   2) When the REG08[2] is 1, will the BQ24295 periodically run input current limit detection and update the input current limit in REG00[2:0]?

   2-1) If yes, after the input current limit detection is done, how long is for the next “input current limit detection” ?

 

Thank you.
