BQ25619: test condition of Ibst in

Part Number: BQ25619

Hi team,

I'm looking at BQ25619 datasheet, find something confused.

In datasheet, the IBST parameter, the test condition is VBAT = 4.5, VBUS = 5V, boost mode enabled. Converter switching.

However, in order to enter boost mode, VBUS should less than VBAT + VSLEEP. So I wander does the above test condition the right one? Could you give some comments on this?

Br,

Will

    Will,

    Thank you for bringing this to our attention and sorry for the confusion. The IBST Line in the electrical characteristics table  should read "VBAT = 4.5V, BOOSTV = 5V, boost mode enabled."  The VBUS being referred to is the boost voltage set by REG06[5:4]. We will address this in the next revision of the datasheet.

    Thanks,

    Ricardo
