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.
