Power Over Ethernet (PoE) Controllers
Power over Ethernet (PoE) controllers allow designers to transmit electrical current and data over a single Ethernet connection. Remote devices are powered through Ethernet cabling, eliminating the need for batteries, local power adaptors and additional power cabling. Bridge rectifier and N+1 O-Ring are two types of PoE controllers. Available features may include N and P-channel FETs, internal switches and automotive certification.
