LTC4267CDHC-3#TRPBF - Brand New Analog Devices / Linear Technology Power Over Ethernet Controllers
-
Description
The LTC4267CDHC-3#TRPBF is a quad PSE controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet systems. It is equipped with external power MOSFETs to enhance system reliability and minimize channel resistance, reducing power dissipation and eliminating the need for heatsinks even at Type 2 power levels. With external power components, it can be used at very high power levels while remaining otherwise compatible with the IEEE standard. The 80V-rated port pins provide robust protection against external faults.
