LTC4267IDHC#TRPBF - Brand New Analog Devices / Linear Technology Power Over Ethernet Controllers
-
Description
The LTC4267IDHC#TRPBF is a quad Power Sourcing Equipment (PSE) controller designed for use in Power over Ethernet (PoE) systems that comply with IEEE 802.3 Type 1 and Type 2 (high power) standards. The external power MOSFETs included in this component enhance system reliability and minimize channel resistance, reducing power dissipation and negating the need for heatsinks, even at Type 2 power levels. This controller is also compatible with high power levels while staying within the IEEE standard. Moreover, there are 80V-rated port pins that provide protection against external faults.
Specifications and features
The LTC4267IDHC#TRPBF has the following features:
- Four independent PSE channels
- Compliant with IEEE 802.3at Type 1 and 2
- 0.34Ω Total Channel Resistance
- 130mW/Port at 600mA
- Advanced power management including 8-bit programmable current limit (ILIM), 7-bit programmable overload currents (ICUT), fast shutdown of preselected ports, 14.5-bit port current/voltage monitoring, and 2-event classification
- Very high reliability 4-point PD detection with 2-point forced voltage and 2-point forced current
- High capacitance legacy device detection
- LTC4259A-1 and LTC4258 pin and SW compatible
- 1MHz I2C-compatible serial control interface
- Midspan backoff timer
