TPS2388RTQT

Overview

The TPS2388RTQT is an eight-port Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3at standards. It operates at a supply voltage of 48 V and functions within a temperature range of -40°C to +125°C. The device utilizes a QFN-56 surface-mount package and draws a typical operating current of 10 mA. Designed for high-density applications, it integrates management features for PoE LAN systems.

Feature Summary

• Supports eight-channel power delivery compliant with IEEE 802.3at specifications
• Integrates comprehensive port management and monitoring capabilities
• Operates reliably across extended industrial temperature ranges

Applications

• High-density Power-over-Ethernet switch designs
• Industrial networking infrastructure equipment
• Access point aggregation systems requiring multiple powered endpoints

Procurement Notes

Verify the specific suffix RTQT against the manufacturer datasheet to confirm the tape-and-reel packaging configuration. Ensure compatibility with the intended PCB footprint for the QFN-56 package. Confirm that the design supports the required 48 V input voltage and thermal dissipation needs for the target environment.

Selection Notes

Select this component when designing systems requiring eight independent PoE ports under the 802.3at standard. It is suitable for applications needing integrated port management rather than discrete switching solutions. Consider the QFN-56 package constraints and thermal performance requirements during the layout phase.

Part Context

This part belongs to the Texas Instruments TPS2388 family of PoE controllers. It serves as a centralized solution for managing multiple powered devices over Ethernet connections. The device simplifies system architecture by integrating control logic and protection features into a single compact package.

Replacement Considerations

The TPS23880RTQR is documented as a related variant within the same product family. Verify functional equivalence and pinout compatibility before substitution.
