Note1: 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 "recom-

mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device

reliability.

Note 2: Please refer to “Thermal Pad Consideration”. 2 layered 5 in2 printed circuit boards with 2oz trace and copper through several

thermal vias. The thermal pad is soldered on the PCB.

Note 3: The case temperature is measured at the center of the exposed pad on the underside of the TQFN3x3-16 and TQFN4x4-20B

packages.
