Document Number: 001-12696 Rev. *E
Notes
12. T
13. To achieve the thermal impedance specified for the QFN package, the center thermal pad must be soldered to the PCB ground plane.
14. Higher temperatures may be required based on the solder melting point. Typical temperatures for solder are 220 ± 5
Refer to the solder manufacturer specifications.
