(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1) Maximum power dissipation is a function of T
J
(max), θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P
D
= (T
J
(max) – T
A
)/ θ
JA
. Operating at the absolute maximum T
J
of 150 ° C can affect reliability. Due to variations in
individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power
levels slightly above or below the rated dissipation.
(2) For packages with exposed thermal pads, such as QFN, PowerPAD™, or PowerFLEX, θ
JP
is defined as the thermal resistance between
the die junction and the bottom of the exposed pad.
