TPS23750PWPRG4

Power Over Ethernet (PoE) Controllers Overview

The TPS23750PWPRG4 is an integrated IEEE 802.3af Powered Device (PD) and DC/DC controller manufactured by Texas Instruments. It supports input voltages up to 100 V and operates within a junction temperature range of -40°C to +125°C. The device is housed in a 20-pin HTSSOP package with exposed thermal pad. It integrates classification, surge current limiting, and a buck converter for downstream power delivery.

Power Over Ethernet (PoE) Controllers Feature Summary

• Integrates IEEE 802.3af PD interface with a high-voltage buck DC/DC controller
• Supports Class 0 through Class 3 powered device classification
• Includes internal surge current limiting and soft-start functionality
• Features comprehensive protection against overvoltage, undervoltage, and overtemperature

Power Over Ethernet (PoE) Controllers Applications

• IP telephony systems
• Wireless access points
• Network surveillance cameras
• Industrial Ethernet field devices

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the complete part number including the 'RG4' suffix to confirm lead-free and RoHS compliance status. Ensure the HTSSOP-20 package variant matches the target PCB footprint. Confirm the specific revision level required for the design to align with manufacturing availability and datasheet specifications.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component when designing systems requiring a single-chip solution for both PoE classification and voltage regulation. It is suitable for applications needing isolation between the PoE port and the load. Consider thermal performance due to the high input voltage handling capabilities inherent in the integrated architecture.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the TPS2375x family of integrated PoE controllers. It serves as a monolithic alternative to discrete solutions combining a PD controller and a switching regulator. The device simplifies board layout by integrating high-voltage switches and control logic for 802.3af compliant networks.

Power Over Ethernet (PoE) Controllers Replacement Considerations

The TPS23750PWP is the non-RoHS equivalent. The TPS23750PWPR is the reel version without the RG4 suffix. Verify pin compatibility and electrical parameters before substituting with other IEEE 802.3af controllers from different manufacturers.
