Abstract:
A Power over Ethernet electrostatic discharge protection circuit has a first diode with an anode coupled to a positive power port and a cathode coupled to an ESD protection port. A second diode has an anode coupled to ground and a cathode coupled to the positive power port. A third diode has an anode coupled to a negative power port and a cathode coupled to the ESD protection port.
