Analog Devices LTC4291 and LTC4292 Digital Controller | Digi-Key Daily

The LTC4291 and LTC4292, from Analog Devices, are four-port power sourcing equipment controllers designed for use in IEEE 802.3bt Type 3 and 4 compliant Power over Ethernet systems. Also, this chipset series is designed to power compliant 802.3af, 802.3at, and 802.3bt powered devices. Powered device detection uses a proprietary multipoint detection mechanism ensuring excellent immunity from false powered device identification. These ICs deliver the lowest-in-industry heat dissipation by utilizing low-RDS(ON) external MOSFETs and 0.15 ohm sense resistance per power channel. Advanced power management features include per-port 14-bit current monitoring, programmable current limit, and versatile, fast shut-down of preselected ports. A transformer-isolated communication protocol replaces expensive optocouplers and complex isolated 3.3 volt supply, resulting in significant BOM cost savings.
