PoE to USB-C adapter extends reach of USB Type-C devices

Microchip Technology Inc. has introduced a power over Ethernet (PoE) to USB-C adapter, solving the issue of limited USB cable length and the need for a nearby power outlet. The PoE to USB-C adapter, PD-USB-DP60, connects IoT devices with a USB-C connector over PoE, leveraging the benefits of both PoE and USB-C technologies.

USB Type-C connectors offer fast data rates and fast power delivery but can only transmit power up to 10 ft. or 3 meters, while Ethernet cables can transmit power and data up to 328 ft. or 100 meters.

The adapter is compatible with USB 2.0 and 3.1 and automatically provides the exact amount of power to the end device. It’s also plug and play, so no configuration is needed.

Claiming the highest power capability, the adapter converts both power and data while offering up to 60 W USB output power via an Ethernet cable up to 328 ft./100 meters from the location of the USB-C device. This is in comparison to most adapters in the market that provide only power up to 25 W, said Microchip.

The adapter can accept up to 90 W of PoE and convert it to 60-W output over USB-C, which means it can power most cameras, laptops, tablets, small PCs, smart monitors, information kiosks, and other devices using USB-C for input power. In many cases today, a USB Type-C port is the only input power option for these devices.

Microchip noted that the adapter enhances the remote power management capabilities of the USB-C power device. The remote power reset capability, provided by the PoE source, allows power cycling via web interface or Simple Network Management Protocol (SNMP) to reset the device, eliminating the need to manually unplug and restart at the equipment location.

In addition, it enables the use of PoE in applications not previously possible thanks to the capability of converting 90-W input to 60-W output. The adapter can be paired with Microchip’s single-port and multi-port (up to 24) PoE injectors/midspans and switches that comply with IEEE 802.3af/at/bt industry standards and provide up to 90-W power per port. If a lower power is needed to power the USB-C device, IEEE802.3af (15.4 W) or IEEE802.3at (30 W) PoE sources can be used, said Microchip.

The PoE to USB-C adapter can connect to a variety of PoE sources and standards. It supports newer IEEE 802.3af/at/bt standards as well as legacy PoE standards. It supports PoE switches and injectors from 15.4 W to 90 W.

Microchip also offers IC solutions that enable the PoE to USB-C adapter, including the PD70xxx family of PoE ICs and the LAN7800 USB-to-Ethernet bridge. The company’s Power Delivery Software Framework (PSF), an open-source Power Delivery (PD) stack that runs on the UPD301C PD controller, provides full PD 3.0 capability and customization for Microchip’s PD controllers, microcontrollers, and USB hubs. Microchip also offers a variety of USB Type-C PD controllers.

The PoE to USB-C adapter is available now for $100.00 each. To purchase products, visit Microchip’s purchasing portal or contact a Microchip authorized distributor.
