Description

SUPP_S1

Input pin for sensing the voltage on the diode bridge connected to the data pairs.

This pin along with the SUPP_S2 pin can be used to distinguish between 2-pair and

4-pair operation. (For PSEs that operate in 4 pairs but generates the classification

procedure on only one pair and not on both pairs). Signal is referenced to VPN_IN.

Place a 10k resistor in the input of this pin.

SUPP_S2

Input pin for sensing the voltage on the diode bridge connected to the data pairs.

This pin along with the SUPP_S1 pin can be used to distinguish between 2-pair and

4-pair operation. (For PSEs that operate in 4 pairs but generates the classification

procedure on only one pair and not on both pairs). Signal is referenced to VPN_IN.

Place a 10k resistor in the input of this pin.
