TPS2376DR

Overview

The TPS2376DR is a Powered Device controller compliant with IEEE 802.3af standards, designed for Power over Ethernet applications. It operates within a voltage range of 0 V to 57 V and features a maximum on-resistance of 1 Ohm. The device limits current to 405 mA and delivers an output power of 12.95 W. It functions in temperatures from -40°C to +85°C with a quiescent supply current of 240 uA. Packaged in an SOIC-8 surface-mount format, it integrates classification and protection logic.

Feature Summary

• Integrates classification logic to identify powered device power class
• Provides comprehensive protection against reverse polarity and short circuits
• Supports hot-swapping capabilities for safe connection to live Ethernet lines

Applications

• IEEE 802.3af Powered Device implementations
• VoIP telephony systems
• Wireless LAN access points
• Network surveillance cameras

Procurement Notes

Verify the specific suffix 'DR' confirms the SOIC-8 tape-and-reel packaging configuration. Ensure compatibility with existing IEEE 802.3af infrastructure requirements. Confirm that the operating temperature range meets environmental specifications. Validate pinout alignment with design schematics prior to integration.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af protocols. Consider the SOIC-8 package constraints for PCB layout. Evaluate thermal performance given the 12.95 W output capability. Compare against higher-power alternatives if system demands exceed standard classifications.

Part Context

This part belongs to the TPS2376 series of PoE controllers manufactured by Texas Instruments. It serves as a core control element for managing power delivery in networked devices.
