Power Over Ethernet (PoE) Controllers have become extremely popular with their ability to deliver power and data over a single twisted pair cable. The SI3452A-B02-GM, made by Silicon Labs, is a single-port PoE Controller operating up to 30W of output power. It is an Intelligent Power Allocation (IPA) PoE controller, which means it is capable of sensing the power support levels of powered devices, and it is IEEE 802.3bt compliant to provide maximum power in a forward compatible manner. This makes it extremely suitable for industrial applications, and it is typically used in IoT gateways, ATMs, and appliance control systems.

The SI3452A-B02-GM is mainly composed of two parts: Power-Negotiation module and PoE Protection Control module. The Power-Negotiation module has two signal inputs and two signal outputs, which allows it to detect the Class of PD, support the power negotiations, and detect the connection status of PD. It also contains a PoE control circuit, which monitors the PoE parameters and issues the appropriate control signal to the PoE load such as the load disconnect signal. The PoE Protection Control module is designed to protect the PD port against ESD and other over-current events.

The SI3452A-B02-GM implements full PoE-Powered Device (PD) classification and intelligent power allocation based on IEEE802.3bt Type 3/2. It is also capable of rapid performance detection to allow PDs to come up quickly. The device includes a wide range of safety features such as a thermal protection circuit, PWM short-circuit protection and reverse polarity protection. It also features over-current protection and supports current limit control. Furthermore, the device is able to support both single-pair and two-pair PoE connections.

In addition, the device features a highly-optimized power delivery system, allowing it to provide high-efficiency power conversion. This system includes a built-in switch mode power supply that enables it to start-up quickly and dynamically adjust its power output. The device also integrates a low quiescent current linearly-regulated control circuit, which helps to distribute power efficiently and accurately. With all these features, the device can provide high-efficiency, reliable and safe power delivery for a variety of applications.

The SI3452A-B02-GM is a highly efficient and intelligent PoE Controller, which is ideal for applications requiring a low-cost, single-port solution with high-power delivery. It is also very suitable for industrial applications, due to its built-in safety features, advanced power delivery system and wide range of robust protection capabilities. With its easy-to-use interface, this single-chip solution offers fast, efficient and reliable power delivery.
