TPS2372-4RGWR

Power Over Ethernet (PoE) Controllers Overview

The TPS2372-4RGWR is a high-power Power over Ethernet (PoE) Powered Device (PD) interface controller compliant with IEEE 802.3bt standards. It supports Type 4 power levels, enabling up to 90 W at the PSE and approximately 71.3 W at the PD input across 100 meters of CAT5 cable. The device integrates a robust 100 V hot-swap MOSFET with a typical on-resistance of 0.1 Ω and a current limit of 2.2 A. Key features include automatic Maintenance Power Signature (MPS) for ultra-low power standby, Autoclass functionality for system power optimization, and a PG output with surge completion delay. It operates within a junction temperature range of -40°C to 125°C.

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the specific suffix RGWR against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with IEEE 802.3bt Type 4 infrastructure. Confirm thermal management requirements for the VQFN package under maximum load conditions. Validate that the supply chain source provides genuine components with traceable manufacturing data.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component for designs demanding maximum PoE power delivery efficiency. The integrated MOSFET reduces external component count compared to discrete solutions. Consider the 0.1 Ω on-resistance for thermal planning in compact enclosures. Verify that the application circuit supports the required Autoclass signaling for optimal power negotiation with the PSE.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the TPS2372 family, which includes variants supporting different power tiers. While the TPS2372-3 handles Type 3 applications, the TPS2372-4 variant is engineered for higher wattage demands. The family shares common control logic but differs in internal switch ratings and current limits to match specific power class requirements.
