PRODUCTION DATA.
The charger has fixed ACOV voltage. When VBUS pin voltage is higher than ACOV, it is considered as adapter over voltage. CHRG_OK will be pulled low, and converter will be disabled. As system falls below battery voltage, BATFET will be turned on. When VBUS pin voltage falls below ACOV, it is considered as adapter voltage returns back to normal voltage. CHRG_OK is pulled high by external pull up resistor. The converter resumes if enable conditions are valid.
