Microchip Power-Efficient PoE PSE ICs
PD77020 & PD77728 - Power-efficient Gen 7 PoE PSE chipsets with improved surge protection
Increase the robustness and reliability of PoE systems
Power over Ethernet (PoE) is a technology that delivers both power and data over a standard Ethernet cable. Devices such as Wi-Fi Access Points, IP Security cameras and IP Phones that utilize PoE are referred to as Powered Devices (PDs). PoE Power Sourcing Equipment (PSE) are devices that deliver power to these PoE-enabled PDs. PoE PSEs include PoE switches, PoE midspans/injectors and wireless routers. The key benefit of PoE is the elimination of the external power supply and flexibility in device placement.
The PoE Team at Microchip has been developing PoE solutions for over 25 years. Over time, they have contributed to the IEEE Ethernet standards for PoE and developed several IEEE 802.3af/at/bt-compliant PoE ICs and systems. Building on the success of their previous solutions, they are now introducing their seventh-generation PSE chipset with enhanced power management and surge protection features to reliably power PoE switches, PoE midspans/injectors and wireless routers.

Microchip PoE Powers Networks
PoE Technology Empowering Networks
PoE technology simplifies installation by transmitting power and data over a single Ethernet cable, enabling quick setup for devices like Ethernet switches, wireless access points, IP cameras, lighting controls, patient monitoring systems, and POS terminals.
Its versatility makes it suitable for various network environments, including wireless, security, smart building, healthcare, and retail networks. PoE addresses key network challenges such as fast and cost-effective installation, handling increased data traffic, providing a reliable power source, and offering remote power management. Additionally, it ensures flexibility, scalability, and energy efficiency. Overall, PoE is widely adopted for its comprehensive benefits.
The PoE Legacy
Microchip is a pioneer and market leader in PoE technology, having introduced the first Power Sourcing Equipment (PSE) IC and Powered Device (PD) IC onto Ethernet infrastructure. Microchip identified the need for power in switches and created the first PoE midspan/injector to deliver both data and power.
Microchip also introduced outdoor and multi-Gigabit PoE midspans and has significantly contributed to the IEEE 802.3af/at/bt standards. They continue to innovate, focusing on supporting new applications requiring higher power and greater speed, for both indoor and outdoor uses. Microchip advancements aim to reduce operating expenses and facilitate faster deployment.
