ZHCSVT2A April 2022 – April 2024 BQ76922
PRODUCTION DATA
The BQ76922 device includes two voltage references, VREF1 and VREF2, with VREF1 used by the voltage ADC for most measurements except external thermistors. VREF2 is used by the integrated 1.8V LDO, internal oscillators, and integrated coulomb counter ADC. The value of VREF2 can be measured indirectly by the voltage ADC's measurement of the REG18 LDO voltage while using VREF1 for diagnostic purposes.
