TPS2377DR is a Power Over Ethernet (PoE) Controllers manufactured and commercially available from Texas Instruments. It is one of the first switching regulators manufactured which provides a highly integrated, turnkey solution for Power over Ethernet (PoE) applications requiring IEEE 802.3af/at Type 1 compliant PoE interfaces. The device can supplying up to 25W (including all PoE protocols up to 25.5W) of power and combines high surge ratings (3.3kV, 10A) with greater system and surge insulation. This device ensures compliance with IEEE 802.3af/at protocols while providing efficient power delivery and integration of IEEE 802.3af/at features.

The TPS2377DR is designed to deliver power over the Ethernet (PoE) and is suitable for use in a wide variety of PoE applications. It provides an integrated solution for all the Power over Ethernet (PoE) requirements, including for Smart Energy 2.0, Desktop VoIP Phones, RFID Readers, Security Cameras, and PC-based peripherals. The device provides robust protection with over-current, short circuit, and over-voltage protection to prevent damage to connected external device.

The working principle for TPS2377DR is simple. It functions as an 802.3af/at Type 1 switch, handling all PoE-protocol transfers over the PoE cable between the power source and the powered device. The power is provided from the power source, which could be a power supply, or a generator. When the powered device has been identified as a Type 1 device, the source then sends a valid IEEE 802.3af/at Protection frame (MPDU) to announce the presence of the Type 1 Powered Device. When the TPS2377DR receives this frame, it starts the switch operation and provides the valid supply voltage and current to the powered device.

In addition, the TPS2377DR provides additional features such as Power Management Interface (PMPI), Automatic Layer-2 Detection and Configuration, as well as Link Status Detection. The PMPI feature can detect the type of the connected PoE devices, and the current load of connected devices, and adjust the amount of power needed to supply based on the device power requirement. The Automatic Layer-2 Detection and Configuration feature supports auto-negotiation for the IEEE 802.3xLink Status Detection (LSD) to protect the PoE devices against malicious attacks. The Link Status Detection feature monitors the state of the PoE link, and it can detect network breakage, cable disconnection, or other out of socket faults, and automatically disconnects the powered device when a fault has been detected.

The TPS2377DR provides intergrated PoE capabilities for a variety of applications. It provides an innovative and efficient solution for IEEE 802.3af/at Type 1 compliant power over Ethernet. And it is suitable for use in applications where reliability and efficiency are important factors. It is an ideal choice for applications that require advanced PoE capabilities such as for Smart Energy 2.0, Desktop VoIP Phones, RFID Readers, Security Cameras, and PC-based peripherals.
