(1) Operation with VBAT up to 80 V is supported when the charge pump is not in operation. Whenever the charge pump is in operation (in 5.5 V or 11 V mode), the maximum voltage on VBAT should be reduced to ensure the voltage on CP1, CHG, and DSG does not exceed their maximum specified voltage.
(2) The internal pullup resistance includes only the resistance between the REG18 pin and the point where the voltage is sensed by the ADC.
(3) The internal pad resistance includes the resistance between the point where the voltage is sensed by the ADC and the pin where an external thermistor is attached (which includes the TS1, TS2, TS3, ALERT, CFETOFF, DFETOFF, HDQ, DCHG, and DDSG pins)
