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.
