Other Parts Discussed in Thread: BQ25750
hi,Ti'friend,
We had some problems when we tested the BQ25750EVM:
1/
When the BAT is charging and the VSYS is discharging(about >3.2A) simultaneously, then we power off the AC source , the VSYS can not work continuously and the BAT can not discharge(BAT_DRV is not on).
When the BAT is charging and the VSYS is discharging(<3A) simultaneously, then we power off the AC source , the VSYS can work continuously and the BAT can discharge.
(In this situation, we have modified the VBAT_FB 16.8V, ICHG_PIN 3A, ILIM_PIN 6A,ACUV 25V,ACOV 30V,without HOST),
2/
The ILIM_PIN resistor value is not satisfied with 50/R by default.For example, it's not 6A of current limit when the resistor is 8.2K,but much greater.
It seems that there is some Inappropriate control mechanism when switching power path.
Could you give some advice？
Thank you!
