Absolute Maximum Ratings (Cont.)
Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Thermal Characteristics
Note 2: Please refer to “ Layout Recommendation”, the Thermal-Pad on the bottom of the IC should soldered directly to the PCB’ s
Thermal-Pad area that with several thermal vias connect to the ground plan, and the PCB is a 2-layer, 5-inch square area with 2oz
copper thickness.
Note 3: The case temperature is measured at the center of the Thermal-Pad on the underside of the TQFN5X5-32A package.
