Power over Ethernet (PoE) Controllers are widely used in the modern world due to its ability to provide power to devices over a single Ethernet cable. These controllers are powered either externally or by an internal power source, depending on the requirements of the system. The SI3402-B-GMR is a single-port 10/100/1000BASE-T PoE controller which is specifically designed for power over Ethernet applications.

The SI3402-B-GMR is a highly-integrated, low-power, single-port 10/100/1000BASE-T PoE controller with an onboard DC-DC converter. It is designed to provide complete power-over-Ethernet control and management, while also providing maximum flexibility and compatibility with existing Ethernet networks. The SI3402-B-GMR provides power up to 25.5 W at 24 VDC, and is compatible with IEEE 802.3af and IEEE 802.3at standards.

The SI3402-B-GMR provides an advanced feature set that allows it to be easily configured and integrated into a variety of PoE systems. It features Automatic Identification (Auto-ID) of connected powered devices, Automatic Power Swap (APS) which automatically swaps power sources if the primary power source fails, Automatic Detection of Device Status (ADS) which allows it to recognize and report the power and energy requirements of connected powered devices, Power Good and Status Outputs which indicate when the correct voltage and current levels have been achieved, and Energy Control Modes which can be programmed for maximum efficiency.

The SI3402-B-GMR utilizes two primary components to power and control the PoE system. The first component is the power management IC (PMIC), and the second component is the system software. The PMIC is the component which controls the overall power system and manages the power distribution and the flow of power between the powered devices and the PoE system. The software component allows for the user to configure, monitor, and control the system in real time.

The SI3402-B-GMR features a wide input voltage range (9V to 54V) and can manage up to 25.5 W of power. It also features a very low 1 ms input capacitance, which allows it to meet the requirements of a wide range of PoE applications. The SI3402-B-GMR supports a variety of power delivery modes, including power to individual devices or groups of devices, as well as allow for the configuration of sophisticated power delivery algorithms based on the requirements of the application.

The SI3402-B-GMR is an innovative PoE controller that helps to simplify the deployment of PoE applications and provide flexible power options. Its advanced feature set makes it an ideal choice for the deployment of PoE networks in a variety of applications. It provides the power, control, and flexibility necessary to deliver power in an efficient and cost-effective manner.
