PRODUCTION DATA
The charger has fixed ACOV voltage threshold with hysteresis. When VBUS pin voltage is higher than VACOV_RISE for more than 100 μs, it is considered as adapter overvoltage. CHRG_OK pin will be pulled low by the charger, and the converter will be disabled. As system falls below battery voltage, BATFET will be turned on. When VBUS pin voltage falls below VACOV_FALL for more than 1 ms, it is considered as adapter voltage returns back to normal voltage. CHRG_OK pin is pulled high by external pull-up resistor. The converter resumes if enable conditions are valid.
