Notes:
(1) Electrical Characteristics apply for V VIN = 4.75V to 5.25V, but are tested only at V VIN = 5.00V, unless noted.
(2) Sustained operation to VT UVLO-F ≤ V VIN is guaranteed only if a current limited charging source applied to VIN is pulled below VT UVLO-R by
the charging load in adapter mode; forced VIN voltage below VT UVLO-R may in some cases result in regulation errors or other unexpected
behavior.
(3) Not tested. Guaranteed by design.
