Benefit
This solution provides ESD and 
overcurrent protection for 10/100 Base-T 
PoE PSE devices without impairing the 
Ethernet signal.
Objective
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 
Powered-Sourcing Equipment (PSE) unit.
