Part Number:BQ25890
Hello E2E,
Customer is using bq25890 on their system and they found that the VBAT value read back through internal ADC is inaccuracy.
Real measure Vbat by digital meter is only 3.25V, but read back value is 3.8V.
What is the possible reason?
VBAT: read REG0E
VSYS: read REG0F
TBAT: read REG10
BR,
Jason
