DESCRIPTION  
The TPS23841 is a high-power, wide voltage range,  
quad-port sourcing equipment manager. The  
TPS23841 can provide up to 570 mA per port over a  
wide temperature range (-40°C to +125°C). Each  
port may operate from 21.5 V up to 57 V. The

components per port (MOSFET and sense resistor)  
and survives 100-V transients. Four individual 15-bit  
A/D converters are used to measure signature  
resistance, voltage, current and die temperature,  
resulting in a simple and robust PSE solution. The  
TPS23841 comes with a comprehensive software  
solution to meet the most demanding applications  
which can serve as a core for all PoE system  
designs.
