(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
The LDD output time of the maximum current should maintain 25% or less of the xsleep total ON time.
(3)
A lower RθJC is attainable if the exposed pad is connected to a large copper ground plane. RθJC and RθJA are values for 56-pin TSSOP
without a exposed heat slug (HSL) on bottom. Actual thermal resistance would be better than the above values.
7.2 ESD Ratings

C101(2)
(1)
JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2)
JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
