Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters

specified in the Electrical Characteristics section is not recommended.

NOTES:

(1)

Tested according to JEDEC standard JESD22-A114D.

(2)

Operating Voltage is the input voltage at which the charger is guaranteed to begin operation. These ranges, VT

ADsel-R

Max to V

OVP-F

Min for the

VAD input, V

UVLR

Max to V

OVP-F

Min for the VUSB input, apply to charging sources operating in voltage regulation. Charging sources operating

in current limit may be pulled below these ranges by the charging load. Maximum operating voltage is the maximum Vsupply as defined in

EIA/JEDEC Standard No. 78, paragraph 2.11.

(3)

Calculated from package in still air, mounted to 3 x 4.5 (in), 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
