LTC4296-1 5-Port SPoE PSE Controller Analog Devices Inc. LTC4296-1 5-Port SPoE PSE Controller is an IEEE 802.3cg-compliant, five port, single-pair power over Ethernet (SPoE), power sourcing equipment (PSE) controller. SPoE simplifies system design and installation with standardized power and Ethernet data over a single-pair cable. The LTC4296-1 is designed for interoperability with 802.3cg-powered devices (PDs) in 24V or 54V systems. The LTC4296-1 delivers power using external, low drain-to-source on resistance (RDS(ON)), N-channel metal-oxide-semiconductor field-effect transistors (MOSFETs), which minimize voltage drop and ensure application ruggedness.
