Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These

are stress ratings only, functional operation of the product at these or any other conditions above those indicated in

the operational section of this specification is not implied. Operation beyond the maximum operating conditions for

extended periods may affect product reliability.

Thermal Resistance

Thermal performance is directly linked to PCB design and operating environment. Careful attention to PCB thermal

design is required. θJA is the natural convection junction-to-ambient thermal resistance measured in a one cubic

foot sealed enclosure. θJC is the junction-to-case thermal resistance.

For θJC test, 100μm thermal interface material (TIM) is used. TIM is assumed to have 3.6W/mK.

ESD Caution

ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can

discharge without detection. Although this product features patented or proprietary

protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore,

proper ESD precautions should be taken to avoid performance degradation or loss of

functionality.
