TMI730ꦕ1 provides a complete interface for a  powered device (PD) to coꦓmply with the IEEE®  802.3af standard in a Power-over-Ethe𒅌rnet (PoE)💞  system. TMI7301 pr🍰ovides the PD with a detection  signature, classification signature, a꧋nd an  integrat🦂ed isolation powﷺer switch with inrush  current♓ control. During the inrush ꦓperiod, TMI7301 limit the curr🉐ent to less than 150mA before  switching to the higher current limit (400mA to &n🍃bsp;500ꦕmA) when t𝓰he isolation power MOSFET is fully  enhanced. T🎉he device features a🦩n input UVLO with  wide hysteresis and long deglitch time to  compens🅰ate for twisted-pair cable resistive drop  and to assure glitch-free t🌊ransition during poweron/-off conditio💙ns. TMI7301 can withstand up to  100V at the input. TMI7301 also provides a power-good (PG) sigꦰnal, two- step current limit and f💝oldback, over temperature𒀰 protection, and d🍸i/dt limit. TMI7301 automatically🥀 generates the necessary  pulsed current t🌄o maintain the PSE power. An &💦nbsp;external resi💖stor is used to enable this functionality  and to program the MPS pulsed current amplitude
