Pwr The exposed pad at the bottom surface of the package is designed for
thermal performance. Use of a center pad on the PCB is strongly recom-
mended for thermal conductivity as well as to provide mechanical stability
of the package on the PCB. The center pad is recommended to be solder
masked defined with opening size less than or equal to the exposed ther-
mal pad on the package bottom to prevent solder bridging to the outer
leads of the device. Thermal vias must be connected to GND plane as the
thermal pad of package is at GND potential.
