PMIC - Power over Ethernet (PoE) Controllers are responsible for the safety, reliability and efficient management of the power supply on any Ethernet-based communication system. This technology enables the transmission of power and data over the same Ethernet connection, which enhances the applications for suitable alternative power sources for devices. The TPS2375PW-1 is one of the power over Ethernet controllers from Texas Instruments. This particular model stands out from the competition due to its advanced features and superior performance.

The TPS2375PW-1 is designed for processing Ethernet data packets for Power-over-Ethernet PDs (Power Device) Injector applications. Its key features include low RDS(on) MOSFET switches, up to 4kV isolation voltage, integrated Power Saver and sophisticated auto detect features. It also supports up to a maximum of 25W of output power, integrated pruning pads, SR validated parts, over-temperature protection and 48V DC input voltage range.

In terms of applications, this device is suitable for a wide range of DC/DC power supplies, AC/DC adapters, communication systems, LAN and WAN networks, PoE PSEs (Power Source Equipment) and VoIP (Voice over IP) systems. It can also be used in industrial automation and renewable energy systems. Additionally, the TPS2375PW-1 is used in converters, bridges, routers, switches and equipment operating in harsh environment such as extreme temperatures.

The TPS2375PW-1 is also designed for compatibility with IEEE 802.3at Class 4 compliant systems that are designed for advanced power management. This device can detect up to eight PD ports and can provide a dedicated Ethernet cable connection for each port. The device also monitors voltage, temperature and current levels, allowing it to manage the power delivery when needed. This ensures that only the required amount of power is used by the connected device, allowing for a much more efficient power management system.

The working principle of the TPS2375PW-1 is based on the concept of power delivery over the same Ethernet connection. When a PD device is connected to the system, the controller will detect the presence of the device and provide the necessary power to it. The device will then use the power to start up and function properly, with the controller managing the power levels to ensure that the device does not use too much power or become overloaded. This feature helps ensure that no single device will draw too much power from the system, resulting in an efficient and safe power management system.

Furthermore, the device also includes both a Power Saver and Auto Detect feature. The Power Saver feature allows the controller to reduce power consumption when no PDs are connected to the system, while the Auto Detect feature is used to detect PDs and provide them with the necessary power. This helps to ensure that there are no disturbances or power fluctuations in the system. The controller also includes a low standby power, which helps to save energy while waiting for PDs to be connected.

Overall, the TPS2375PW-1 is a highly reliable and efficient power over Ethernet controller that can be used for a wide range of applications. Its key features such as low RDS(on) MOSFET switches, 4kV isolation voltage and integrated Power Saver and sophisticated auto detect features make it stand out from the competition. Moreover, its compatibility with IEEE 802.3at Class 4 compliant systems means that it can be used in a variety of DC/DC, AC/DC and communication systems that require more advanced power management capabilities.
