PRODUCTION DATA
The device is powered from the higher of VAC1 or VAC2 (with VAC1 being primary input), VBUS or VOUT (battery). The voltage must be greater than the VVACUVLOZ, VVBUSUVLOZ or VVOUTUVLOZ threshold to be a valid supply. When VAC1 or VAC2 rises above VVACUVLOZ or VBUS rises above VVBUSUVLOZ or VOUT rises above VVOUTUVLOZ, I2C interface is ready for communication and all the registers are reset to default value. The host needs to wait VBUSPRESENT_STAT and VOUTPRESENT_STAT go high before setting CHG_EN =1 and start charging.
