Power over Ethernet (PoE) controllers, such as the PD64012GH, can support the delivery of power over Ethernet cabling in addition to data over the same network. This versatile design allows power and data to be transmitted over an Ethernet connection, reducing the complexity and cost of wiring, installation and maintenance. In addition to being able to send both data and power over a single Ethernet cable, PoE also provides improved cabling protection, as the combined power and data are carried by a single Ethernet cable instead of multiple circuits.

The PD64012GH is a low power, high-speed PoE controller with two differential pairs of power source and power sink enables, each with a maximum control current of 3.2A. The device includes two individual power source enable drivers that support different power output levels to provide flexible power delivery for all types of powered devices. An integrated, differential surge clamp with an adjustable threshold voltage protects the line from valid or invalid strikes of surge current. The controllers are designed to manage and control the power feeding of external PDs (Powered Devices) over an Ethernet line from a power source or other power sources.

The integrated DC/DC converter works with the LDO to delivery of up to 3.2A of maximum control current for the power sink with an adjustable output voltage range of 18V to 57V. The PD Detect and Shutdown pin allows the device to detect whether the PD placed at the end of the Ethernet cable is supported by the PD64012GH, and enables the shutdown of the unit when the PD is in a disconnection state. A full Protection Circuit provides advanced protection against overheating, over current, overvoltage and short-circuit conditions.

The PD64012GH is targeted at industrial Ethernet applications requiring the transmission of both data and power through a single Ethernet cable. It is well suited for DMX512 systems, IP contact closed circuit surveillance cameras, industrial Ethernet lighting systems and IoT (Internet of Things) applications. In addition, the device supports auto-detection of the PD power class, enabling optimized power delivery performance.

In summary, the PD64012GH is a versatile and efficient power over Ethernet (PoE) controller designed for applications requiring the transmission of both data and power through a single Ethernet cable. The device features integrated DC/DC conversion, LDO and protection circuit. The device also supports auto-detection of the PD power class and offers adjustable output voltage range from 18V to 57V, along with a surge clamp with an adjustable threshold voltage for additional protection. With its flexibility and low power consumption, the PD64012GH is ideal for Industrial Ethernet applications such as DMX512 systems, IP contact closed circuit surveillance cameras, industrial Ethernet lighting systems, and IoT applications.
