TPS2373-4RGWR Application Field and Working Principle

Power Over Ethernet (PoE) controllers are a type of PMIC (power management integrated circuits) that allow for securely transmitting power and data to Ethernet-enabled devices. These devices are essential components in most modern technology, from routers and switches to security cameras and audio equipment. The TPS2373-4RGWR is a PoE controller produced by Texas Instruments that has become one of the industry standards in PoE applications. In this article, we\'ll discuss the application field and working principles of the TPS2373-4RGWR.The TPS2373-4RGWR is a four-channel PoE controller that can detect and supply up to 30 watts of power to up to four different devices. It can be used in blended power designs, where it can detect and provide power to both IEEE 802.3af compliant PoE devices as well as non-PoE devices. The controller features integrated circuit protection features such as over-voltage, over-current and short-circuit protection to ensure safe operation of the devices connected to it.The TPS2373-4RGWR is a highly integrated controller, featuring a built-in DC/DC converter and a programmable interface. It also has a high-current power MOSFET integrated, which allows for more efficient switching and enhanced reliability. Furthermore, the controller also has an on-chip voltage supervisor which enables the controller to detect and communicate an Over-Voltage Protection (OVP) condition to the connected device.The TPS2373-4RGWR is primarily used as a PoE interface circuit in small-form-factor PoE applications such as wireless access points, IP-based cameras, VoIP phones and other Ethernet-enabled devices. The device can detect both 802.3af compliant and non-compliant PoE devices thanks to its programmability, and it can provide power and data to multiple devices at once.When it comes to the working principle of the TPS2373-4RGWR, the device uses a 4 or 5-pair DC detection method to detects PoE devices. Its programmable interface allows it to detect both 802.3af compliant and non-compliant devices, and it can supply up to 30 watts of power to multiple devices at once. The on-chip voltage supervisor will detect a voltage rise and activate the high\MOSFET switch, supplying power to the connected device.Overall, the TPS2373-4RGWR is a highly integrated and versatile power over ethernet controller that has become an industry standard for PoE applications. It is capable of supplying up to 30 watts of power to four devices at the same time, and it is equipped with safety features such as over-voltage and over-current protection. Moreover, its programmable interface allows it to detect and supply power to both 802.3af compliant and non-compliant PoE devices.
