Power over Ethernet (PoE) Controllers enable the delivery of power and data through a single network cable. They make use of a power supply to provide power to powered devices such as VoIP phones, surveillance cameras and wireless access points. The TPS2376DRG4 is an integrated PoE controller from Texas Instruments that contains both a power and data interface. In this application field, it can be used in a variety of commercial and industrial applications.

The TPS2376DRG4 consists of a power MOSFET switch, a linear regulator, and a digital control circuit. It is capable of providing up to 24 W of power and is compliant with the IEEE802.3af/at(PoE) standard. It offers a wide operating temperature range from -40C to +85C, making it suitable for use in harsh environments. It is designed to provide high efficiency, excellent reliability, and cost-effective performance.

The TPS2376DRG4 has two main working modes – PD (power device) and PSE (power sourcing equipment). In the PD mode, the PD is powered by the PSE, up to a maximum of 24W. The TPS2376DRG4 monitors the voltage, current and temperature from the PD and provides protection against over-current, over-voltage and over-temperature conditions. In the PSE mode, the TPS2376DRG4 receives power from the external power source, and provides the PD with power by controlling the power MOSFET switch. The system is designed to enable power management with enhanced efficiency and safety.

The TPS2376DRG4 supports a wide range of applications including VoIP phones, surveillance cameras, access points and more. It enables system designers to add PoE capability to their designs quickly and cost-effectively, while providing protection against overloads, short circuits and temperature variations. It also provides a high level of protection against ESD, EFT, and surge immunity. As such, it is well-suited for use in commercial and industrial applications where reliability and performance are key requirements.

In summary, the TPS2376DRG4 is an integrated PoE controller from Texas Instruments that provides up to 24 W of power and complies with the IEEE802.3af/at(PoE) standard. It is suitable for commercial and industrial applications, as it has a wide operating temperature range, excellent reliability and cost-effective performance. It enables system designers to add PoE capability quickly and cost-effectively, and provides protection against overloads, short circuits, ESD, EFT and surge immunity.
