Notes:

4. Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings

only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device

reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time

5. DFN2020C-6 exposed pad soldered to minimum recommended landing pads (see Package Outline Dimension section) on a two-layer 2oz.

copper FR4 PCB (1.6mm thickness) with no thermal vias in exposed PADs or any copper flood connecting to the landing pattern of the

exposed pad.
