See Charger Sleep mode for ACPG (V

) and USBPS (V
CC

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