Description

This reference design showcases a Type-3: 30W: 2-Pair 24-port Ethernet switch for Power over Ethernet (PoE) applications which can send up to 30W per port for IEEE 802.3bt Type 3 applications and up to 60W per port for non-standard applications. Based on the MSP430F523x family: TI's TPS2388x FirmPSE system firmware provides a total system level solution for multi-port applications which reduces time to market and frees-up valuable software resources. This design supports port power management with priority: multiple power supplies: legacy PD detection: field upgradability: UART/I2C communication with the host: and more. TI’s FirmPSE system firmware GUI for this design enables the customization of production level PSE system firmware code with just a few clicks of a button and provides real-time communication to the system. In addition: two of these designs may be cascaded through the edge connectors in order to support up to 48-port PSE systems.The full PoE Evaluation ecosystem includes the following (optional companion tools also listed): 24 Port PoE PSE Evaluation SystemPSEMTHR24EVM-081: Mother board for 24 Port PoE PSE applications (sold separately)TPS23881EVM-083: TPS23881 daughter card for 24 port Type 3/Type 4 4-Pair (90W) PoE PSE applications (sold separately)TPS23882EVM-084: TPS23882 daughter card for 24 port Type 3 2-Pair (30W) PoE PSE applications (sold separately)PSEMCUDAUEVM-082: MSP430 daughter card for 24 Port PoE PSE applications (sold separately)MSP-FET: Used with PSE system firmware GUI to flash code into MSP430 device (sold separately)USB2ANY Interface Adapter: Used with PSE system software GUI for I2C/UART Interaction with PSEMCUDAU-082 daughter card (sold separately)PSE system software code imageTPS2373 Evaluation Module for IEEE 802.3bt PoE PD ApplicationsTPS2372-4EVM Evaluation Module for IEEE 802.3bt PoE PD ApplicationsTPS2372-3 IEEE 802.3bt Type 3 PoE PD Evaluation Module for Lighting
