Microchip’s new generation of PoE Powered Devices (PD) ICs for IoT Applications, PD70xx series


Our PD ICs, available with or without integrated Pulse-Width Modulation (PWM) controllers, are compact solutions for converting Power over Ethernet (PoE) input power into one or more output voltages in a PD. Our IdealBridge™ dual-pack MOSFET-based full-bridge rectifier protects against reverse-polarity connections while reducing power consumption and space requirements and improving improving thermal performance in a variety of applications, including:

  • WLAN access points
  • 5G small cells
  • Network cameras
  • LED lighting
  • IoT appliances
  • IP telephones

Key Features:

  • IEEE 802.3bt PD ICs are in Development for 60W & 90W solutions, first samples will be available soon, please get in contact at
  • Comply with industry standards such as IEEE 802.3af/at and Power-over-HDBaseT (PoH)
  • Complementary IdealBridge: Enhance efficiency and reduce thermal dissipation
  • Optional integrated PWM controller
    • Secondary Gate Driver (SG) to support synchronized rectification and higher efficiency
    • Power off DC bulk cap discharge – guarantees less than 0.5s quick turn off / turn on time
  • Robust and Reliable design:
    • Higher operating temperature (150C vs 125C) and thermal shutdown protection (180C vs 135-150C)
  • Offer the highest integration level and lowest total BOM cost
  • Leverage a mixed portfolio of devices that can be used in indoor, outdoor and industrial applications
  • Meet the high powering needs of 2-pair and 4-pair PDs including IEEE® 802.11ac/ax access points, information kiosks, POS terminals, thin clients, 5G small cells, industrial automation systems and connected LED luminaires/sensors

As a pioneer in PoE technology, Microchip is the only supplier of PoE PD ICs, PoE Power Sourcing Equipment (PSE) ICs, PoE systems (midspans/injectors and switches) and test equipment.
