Global logistics network for fast worldwide delivery

Power over Ethernet (PoE) technology enables simultaneous transmission of data and power through standard Ethernet cables (such as Cat5e or higher), eliminating the need for separate power cabling. This technology is particularly suitable for the following scenarios:

Network devices installed in locations where power access is difficult (e.g., ceiling-mounted wireless access points)

Simplified cabling to reduce installation costs (e.g., IP surveillance camera systems)

Critical mission-critical devices requiring high reliability (e.g., VoIP phones, security systems)

Applications requiring centralised power management (e.g., smart building automation systems)

Microchip's PoE solutions fully comply with the IEEE 802.3af/at/bt standards, supporting power levels from 15.4W (PoE) to 90W (PoE++), meeting the power requirements of various devices.

Microchip PoE PSE (Power Sourcing Equipment) Integrated Circuit Solutions

The PoE Power Sourcing Equipment (PSE) is the power provider in a PoE system, responsible for detecting, classifying, and supplying power to compliant Powered Devices (PDs). Microchip's PoE PSE integrated circuits offer high efficiency, high integration, and excellent thermal performance, making them an ideal choice for building PoE switches, midspan devices, and injectors.

PSE Application Scenarios

Enterprise-level PoE switches: Powering IP phones, wireless APs, and surveillance cameras in office environments

Industrial PoE switches: Powering industrial sensors and controllers in harsh environments

Security system power supplies: Reliably powering multiple IP cameras in a centralised manner

Smart building systems: Powering IoT devices such as lighting control and access control systems

Microchip PoE PD (Powered Device) Integrated Circuit Solutions

PoE Powered Devices (PDs) are end devices that receive power from PSEs, featuring high integration, low power consumption, and high reliability, and can be widely applied in various network end devices.

PD Application Scenarios

IP cameras and video surveillance systems: Simplify installation and enhance reliability

Wireless access points (WAPs): Enable flexible deployment and centralised power management

VoIP phones: Provide data and power over a single network cable

Industrial IoT devices: Powering remote sensors and controllers

Digital signage and information kiosks: Simplifying device installation in shopping malls and public spaces

Complete PoE system features:

Single-port and multi-port PoE midspans/injectors and switches enable seamless deployment of PoE technology for Ethernet-based devices in indoor, outdoor, and industrial environments
