TPS2384APAPR

Overview

The TPS2384APAPR is a quad-port Power Sourcing Equipment (PSE) power manager compliant with the IEEE 802.3af standard. It integrates four independent channels, each featuring an integrated switch and sense resistor for precise current monitoring. The device operates at a supply voltage of 48 V with a maximum on-resistance of 1.8 Ohms per channel and a current limit of 450 mA. Designed for surface-mount installation in HTQFP-64 packages, it supports operating temperatures from -40°C to +125°C.

Feature Summary

• Integrates four independent power management channels with built-in switches and sense resistors
• Fully compliant with IEEE 802.3af PoE standards for reliable equipment classification
• Provides comprehensive protection mechanisms including over-current and thermal shutdown

Applications

• Quad-port Ethernet switches requiring integrated PSE functionality
• Power sourcing equipment for IEEE 802.3af compliant endpoints
• Network infrastructure devices managing multiple powered devices simultaneously

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence when ordering. Confirm package availability as the HTQFP-64 may have limited stock or longer lead times compared to tape-and-reel variants. Ensure design compatibility with the 48V input range and thermal requirements for the intended operating environment.

Selection Notes

Select this component for designs requiring four isolated PoE ports managed by a single controller. Compare against the TPS23841 series if higher current limits or wider voltage ranges are needed. Ensure the PCB layout accommodates the HTQFP-64 footprint and thermal dissipation needs for continuous operation at maximum load conditions.

Part Context

This part belongs to the Texas Instruments TPS2384 family of quad-port PSE managers. It serves as a core component for integrating PoE capabilities into network hardware without external discrete switching components. The AP variant typically denotes automotive-grade qualification or specific temperature range extensions within the broader product line.

Replacement Considerations

The TPS2384PAPR is a direct functional substitute within the same family. Verify pinout compatibility and ensure the replacement meets the same IEEE 802.3af compliance requirements.
