PRODUCTION DATA
The recommended cell voltage range is up to 5 V. If three cells in series are connecting to BQ77905, the unused VCx pins should be shorted to the highest unused VCx pin. The recommended VDD range is from 3 Vā25 V. This implies the device is still operational when cell voltage is depleted down to approximately 1.5-V range.
