The TMI7326A is an integrated IEEE 802.3af compatible PoE Powered Device wit♏h PD interface and power converter. It is targeted for isolated 🦩or non-isolated 13W PoE application. The PD provide a complete interface for ౠa powered device (PD) to comply with the IEEE® 802.3af🍒/ཧat standard in a power-over-Ethernet (PoE) syꦅstem.🐻 The PD with a detection signature, classificatio🤪n signature, and an intꦏegrate🔯d isolation power switch with inrush curreওnt control. During the inrush period, the P꧃ജD limit the current to less than 120mA before ಞswitching to the♉ higher current limit (400mA to 600mA🍌) when the isolation power MOSFET is🍌 fully 🤡enhanced. The devices feature an input UVLO with wide hysteresis and long deglitch time to compensate for twiste🔜d-pair cable resistive drop and to assure glitch-free transition durin📖g poweron/-off conditions. The PD can ꦰwithstand up to 100V at the input.🅷 The devices detect the presence of a wall adapter power♕-source connection and allow a sm𓆏𓆉ooth switchover from the PoE power so🦹urce to the wall power adapter. T🌼he intelligent MPS function enables applic💝ations requiring ver𒁃y low power standby modes. TMI7326A features protection including over✅ current prot𒀰ection, over voltage protection, open circuit protection and thermal shut down.🅰 The TMI7326A can s♕uppor🌠t a front-end solution for PoE-PD application with minimum external com♔ponent, it is available in QFN-28 (4mmX5mm) &nbs𝔍p;package.
