Si3474 Power Source Equipment (PSE) ICs

Skyworks Solutions Inc. Si3474 Power Source Equipment (PSE) ICs add up to four 90W 802.3bt PSE PoE ports or up to eight 30W 802.3at/af PoE ports. These ICs provide a versatile solution for industrial and commercial Ethernet switches and security recording equipment. The Si3474 ICs can be operated in autonomous mode with full power on each port or in hosted I²C configurable mode. These devices improve thermal performance using a 200mΩ sense resistor option or uses industry-standard 255mΩ. The Si3474 ICs are available in a 56-pin 8mm x 8mm package with an industry-standard pinout.
