Ethernet - Power Over Ethernet (PoE) PD Solution

Ethernet
10/100 Base-T Power over Ethernet (PoE) PD Unit Protection
Solution Products
CDSOT236-0504C
Objective
Alternate Recommendations
10/100 Base-T Power over Ethernet (PoE)
interfaces combine data and 48 V DC to provide
remote power to a Powered Device (PD). This
solution provides ESD and overcurrent protection
for the PD unit.
