Application Information (Cont.)

Thermal Pad Consideration (Cont.)

be as large as practical. If the ambient temperature is

higher than 25°C, a larger copper plane or forced-air cool-

ing will be required to keep the APA3002 junction tem-

perature below the thermal shutdown temperature

(150°C). In higher ambient temperature, higher airflow

rate and/or larger copper area will be required to keep the

IC out of thermal shutdown. See TQFP7x7-48 thermal

pad layout recommendation.
