The TPS2398DGKR is a highly integrated power management integrated circuit (PMIC) component designed for use in power over Ethernet (PoE) systems. It is manufactured by Texas Instruments and offers a range of key features that make it suitable for various PoE applications.
One of the standout features of the TPS2398DGKR is its ability to provide power sourcing equipment (PSE) functionality, making it ideal for applications where power needs to be delivered over an Ethernet cable to powered devices (PDs). With its integrated PSE controller, it supports both 2-pair and 4-pair PoE systems, complying with IEEE 802.3at and IEEE 802.3bt standards.
The TPS2398DGKR incorporates an innovative current mode control architecture, enabling it to efficiently deliver power to PDs. It offers multiple operation modes, including a legacy mode that allows backward compatibility with non-standard or pre-standard PDs, and a forced mode that enforces the power level to a specific value. This flexibility ensures reliable power delivery under different operating conditions.
To enhance system safety, the TPS2398DGKR integrates comprehensive protection features. It includes overcurrent, short-circuit, and thermal shutdown protection mechanisms to prevent damage to the PSE and PDs. Additionally, it supports advanced classification and detection algorithms, enabling accurate detection and identification of connected PDs.
The device also provides various monitoring and control capabilities to ensure optimum performance
