TIDA-050026-23881
用于多端口应用的 24 端口（PoE 2，4 线对）电源设备参考设计
TIDA-050026-23881
概述
This reference design showcases a Type-4 (PoE 2, 4-Pair) 24-port Ethernet switch for Power over Ethernet (PoE) applications which can send up to 90W per port for for IEEE 802.3bt (PoE 2) applications and up to 120W per port for non-standard applications. Based on the MSP430F523x and MSPM0G1107x families, our FirmPSE system software for this design reduces time to market and frees-up valuable software resources by enabling real-time communication with the system and customization of firmware. This design supports power management with priority, multiple power supplies, legacy PD detection, field upgradability, UART/I2C communication with the host, and more. In addition, two of these designs may be cascaded through the edge connectors in order to support up to 48-port PSE systems.
