PRODUCTION DATA
For this design example, passive PoE is not required so PPD is pulled down to VSS. However, the PPD pin can be used to override the internal hotswap MOSFET UVLO (VUVLO_R and VUVLO_H) when using low voltage adapters connected between VDD and VSS. The PPD pin has an internal 5-μA pulldown current source. As an example, consider the choice of RPPD1 and RPPD2, for a 24-V adapter.
