PRODUCTION DATA.
For proper operation of the bq24753A, VCC must be from 8 V to 24 V. When an adapter is attached, and ACGOOD goes LOW, the system is connected to an adapter through ACFET/RBFET. An external resistor voltage divider attenuates the adapter voltage before it goes to ACDET. The adapter detect threshold should typically be programmed to a value greater than the maximum battery voltage, but lower than the IC maximum allowed input voltage and system maximum allowed voltage.
