TI TPS23841PAPR

控制器（PSE）25 W802.3af（PoE）

Overview

The TPS23841PAPR is a high-power, wide voltage range, quad-port sourcing equipment manager. The TPS23841PAPR 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 integrated output eliminates two external 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 TPS23841PAPR comes with a comprehensive software solution to meet the most demanding applications which can serve as a core for all PoE system designs.

The TPS23841PAPR is available in either 64-pin PowerPAD down (PAP) or 64-pin PowerPAD up (PJD) packages.
