Description
The LTC® 4266 is a quad PSE controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet systems. Featuring 80V-rated port pins that provide robust protection against external faults, this controller is compatible with very high power levels while remaining otherwise fully compliant with the IEEE standard. Using external power MOSFETs enhances system reliability and resistance, cutting power dissipation requirements and eliminating the need for heatsinks even at Type 2 power levels.
