Collection: Power Over Ethernet (PoE) Controllers

Power Over Ethernet (PoE) Controllers enable seamless integration of power and data transmission over standard Ethernet cabling, eliminating the need for separate power supplies in remote device installations. These advanced semiconductor solutions are engineered for high-reliability applications across industrial automation, telecommunications infrastructure, security systems, and building management networks.

Our PoE controller portfolio features cutting-edge technologies including bridge rectifiers for efficient AC-to-DC conversion, N+1 O-Ring redundancy architectures for mission-critical uptime, and automotive-certified designs with integrated FETs that meet stringent AEC-Q100 qualification standards. These controllers support IEEE 802.3af/at/bt standards, delivering up to 90W of power while maintaining data integrity across extended cable runs.

Key Features & Benefits:

Integrated Power Management: Combines power sourcing equipment (PSE) and powered device (PD) functionality with built-in protection circuits
High Efficiency: Advanced MOSFET integration reduces power dissipation and thermal management requirements
Robust Protection: Overcurrent, overvoltage, and thermal shutdown safeguards ensure long-term reliability
Wide Operating Range: Support for -40°C to +125°C temperature ranges in industrial and automotive environments
Flexible Topologies: Compatible with midspan injectors, endpoint PSE, and backhaul power architectures

Target Applications: IP cameras and surveillance systems, VoIP phones and unified communications, wireless access points, industrial IoT sensors and gateways, LED lighting control systems, and building automation controllers.

Explore our comprehensive selection of PoE controllers from leading semiconductor manufacturers, each validated for performance, compliance, and long-term availability in demanding deployment scenarios.
