BQ76PL536A-Q1: What input voltage is Vref derived from?

Part Number: BQ76PL536A-Q1

Hey TI team,

I am observing a rare issue in where CELL_UV/CELL_OV FAULT registers in this ASIC are asserted on bootup. I have some suspicion that there is an unstable Vref and was wondering if you could provide more details on how the internal 2.5V Vref is generated inside the ASIC. Unfortunately, I do not have more data at this moment as this failure occurred in the fleet and do not have the HW with me. Therefore I am just looking for some more information on this.

Is the internal Vref supplied by the LDO? Otherwise, what is signal chain that supplies Vref?
