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 System
    • PSEMTHR24EVM-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 image
  • TPS2373 Evaluation Module for IEEE 802.3bt PoE PD Applications
  • TPS2372-4EVM Evaluation Module for IEEE 802.3bt PoE PD Applications
  • TPS2372-3 IEEE 802.3bt Type 3 PoE PD Evaluation Module for Lighting

Features
  • Configurable GUI and host interface
  • Multi-port power management
  • Ability to cascade two designs through edge connectors to enable 48-port PSE system
  • Supports multiple power supplies
  • Legacy PD capacitance measurement
