BQ25750: Question about asymmetry of VREF_ACUV and VREF_ACOV variations

Part Number: BQ25750

Tool/software:

Hi,

In Page-10 of DATASHEET (*1), the MIN and MAX of VREF_ACUV and VREF_ACOV are asymmetric in difference with respect to TYP.
It seems a little unnatural.
VREF_ACOV MIN 1.194 is symmetrical.
And similarly, if VREF_ACUV MIN 1.094, it is symmetrical.
How is it?

Hi,

I will drop the question about VREF_ACUV.
I guess the TYP of VREF_ACUV is 1.1005V.

Hello Tamura,

Thanks for working with this.

Just for reference, the TYP VREF_ACUV is 1.1V and the TYP VREF_ACOV is 1.2V.

Let me know if you have any other questions.

Best Regards,
Ethan Galloway

Dear Ethan,

I appreciate your quick response and I apologize for asking two questions.
The intent of the questions posed is as follows.

MIN VREF_ACOV - TYP VREF_ACOV and MAX VREF_ACOV - TYP VREF_ACOV have different values as follows, is this correct as stated in DATASHEET?

MIN VREF_ACOV - TYP VREF_ACOV = -0.016
MAX VREF_ACOV - TYP VREF_ACOV = 0.006
