TPS23880RTQR

Overview

The TPS23880RTQR is an IEEE 802.3bt-compliant Power Sourcing Equipment (PSE) controller manufactured by Texas Instruments. It integrates eight independent channels supporting Type-4 power delivery over four pairs. The device operates within a supply voltage range of 3 V to 57 V and features programmable current limits of 425 mA and 1.25 A per channel. It utilizes a 56-pin QFN package and functions as a hot-swap voltage controller with a quiescent current of 6 mA. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Supports high-power Type-4 PoE applications across eight independent channels
• Integrates programmable SRAM for flexible configuration management
• Enables parity code loading and SRAM updates via I2C interface

Applications

• High-density Ethernet switch designs requiring Type-4 power distribution
• Access points utilizing four-pair Power-over-Ethernet
• Industrial networking equipment demanding extended temperature operation

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging format, as variations exist between cut tape and reel configurations. Ensure compatibility with required humidity sensitivity levels and lead-free manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component for systems requiring integrated control of multiple high-power PoE ports. Consider the thermal performance of the QFN-56 package in dense layouts. Evaluate the need for external components based on the specific current limit settings required for the target application.

Part Context

This part belongs to the TPS2388x series of PoE controllers designed for complex network infrastructure. It complements other Texas Instruments solutions like the TPS23881, offering distinct integration levels for power sourcing equipment. The series addresses the growing demand for higher power budgets in modern Ethernet deployments.

Replacement Considerations

The TPS23880RTQT serves as a verified alternative with identical electrical specifications but differs in factory packaging quantity.
