DESCRIPTION  
The TPS2384 is  
a quad-port power sourcing  
•
Controlled Current Ramps for Reduced EMI  
and Charging of PD's Bulk Capacitance  
I2C Clock and Oscillator Watchdog Timers  
equipment power manager (PSEPM) and is  
compliant to the Power-over-Ethernet (PoE) IEEE  
802.3af standard. The TPS2384 operates from a  
single 48-V supply and over a wide temperature  
range (–40°C to 125°C). The integrated output  
eliminates two external components per port (FET  
and sense resistor) and will survive 100-V transients.  
Four individual 15-bit A/D converters are used to  
measure port resistance, voltage, current and die  
temperature making PSE solutions simple and  
robust. The TPS2384 comes with a comprehensive  
software solution to meet the most demanding  
applications which can serve as a core for all PoE  
system designs.
