(16) See Charger Sleep mode for ACPG (VCC = VAC) and USBPS (VCC = VUSB) specifications.
(17) To disable the safety timer and charge termination, tie TMR to the LDO pin.
(18) The IC is considered in sleep mode when both AC and USB are absent (ACPG = USBGP = OPEN DRAIN).
(19) Does not declare sleep mode until after the deglitch time and implement the needed power transfer immediately according to the
switching specification.
