PoE Power Sourcing Equipment (PSE) ICs  

Our PSE ICs portfolio is the broadest in the industry, offering solutions that deliver up to 90W over standard Ethernet infrastructure. These plug-and-play solutions make it easy for system developers to transition to the latest IEEE® 802.3bt standard by enabling both pre-standard and IEEE-compliant PDs to receive up to 90W of power without changing existing switching or cabling.   

Our PSE ICs are used in a variety of applications including:

  • Enterprise, SMB and industrial Ethernet switches 
  • Gateways
  • Routers
  • PD-PSE daisy chain applications

As a long-time innovator in Power over Ethernet (PoE) technology, Microchip is the only supplier of PoE PD ICs, PSE ICs, midspans/injectors and test equipment.

Key Benefits of Our PoE PSE ICs:

  • Comply with IEEE 802.3af/at/bt and Power-over-HDBaseT (PoH) industry standards
  • Offer the highest integration level and lowest total BOM cost 
  • Lowest port resistance, high efficiency and improved thermal performance
  • Flexibility for single design to support 2-pair or 4-pair PoE solutions
  • Meet the high power requirements of 2-pair and 4-pair PDs including 802.11ac/ax access points, information kiosks, POS terminals, thin clients, 5G small cells, smart buildings, industrial automation systems and connected LED lighting luminaires/sensors
  • Upgrade an existing Microchip Gen 6 PSE chipset to the latest IEEE 802.3bt standard via a software update; no hardware changes required
  • Leverage dynamic and emergency power management software capabilities for efficient power supply usage
