TM༺I7302A provides a complete interface for a  powered deviಞce 🐭(PD) to comply with the IEEE®  802.3af standaᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚrd✅ in a Power-over-Ethernet (PoE)  system. TMI7302A provides the PD with a  detec💮tion signature, classification signature, and  an integrated isolation power switch𒉰 with inrush  current control. During the inrush period,  TMI7302A limit the current to less than 1🎶50mA  𝓡before switc🐬hing to the higher current limit (400mA  to 500mA) when the isolation power ꦦMOSFET is  fully enhance🐼d. The✃ device features an input UVLO  with wide hysteresis and long deglitch time to  ꦛ;compensate for twisted꧋-pair cable resi๊stive drop  and to assure glitch-free tran💯sition during poweron/-🌃off condit✤ions. TMI7302A can withstand up to  100V 📖at the input. TMI7302A also provides a  power-good 𓂃(PG) signal, two- step current limit and  fold-back, over temperature protection, and di/dt🐟  limit. TMI7302A automatically generates the necessඣarཧy  pulsed curr🥂ent to maintain the PSE power. An  external resi๊stor is used to enable this functionality  and to program the MPS pulsed current amplitude.
