Notes:
1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This
is a stress rating only and functional operation of the device at these or any other conditions above those indicated
in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Absolute maximum ratings apply individually only, not in combination.
Unless otherwise specified all other voltages are referenced to GND.
2. Junction to ambient thermal resistance, θ_JA, is a strong function of PCB material, board thickness, thickness
and number of via used, diameter of via used, available copper surface, and attached heat sink characteristics.
A reasonable estimated value for θ_JA for zero air flow at 0.5W is 60°C/W.
3. Using Mil Std. 883E, method 3015.7(Human Body Model) and EIA/JESD22C101-A (Charge Device Model).
