BQ25505: wrong datasheet figures

Part Number: BQ25505

There are errors in the datasheet 'simplified schematic' on page 1 and figure 16 (figure 28 and 34 are ok):
VOC_SAMP must not be connected to VSTOR.

And in the forum there was a recommendation
"... to isolate any resistive loads connected at VSTOR using an external PFET with gate drive by /VB_SEC_ON."
This should be mentioned in the datasheet. A load during cold start is a serious problem.

  • Hi Thomas,

    Regarding the datasheet figures, VOC_SAMP can tied to either either VSTOR or GND to force 80% or 50% MPP setting, respectively, without the need for external resistors.

    I agree with your second comment and will recommend the datasheet change.

    Regards,
