(15) To disable the safety timer and charge termination, tie TMR to the LDO pin.

(16) The IC is considered in sleep mode when both AC and USB are absent (ACPG = USBPG = OPEN DRAIN).

(17) Does not declare sleep mode until after the deglitch time and implement the needed power transfer immediately according to the

switching specification.
