TPS2375PWR

Overview

The TPS2375PWR-1 is a Power over Ethernet (PoE) Powered Device controller compliant with IEEE 802.3af standards, manufactured by Texas Instruments. It integrates an internal power switch with a maximum on-resistance of 1 ohm and a current limit of 405 mA. The device operates within a supply voltage range of 0 V to 57 V and supports surface-mount installation in an 8-pin TSSOP package measuring 3 x 4.4 x 1.15 mm. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Complies with IEEE 802.3af PoE standards for powered device classification
• Integrates an internal power switch with low on-resistance
• Includes built-in current limiting protection

Applications

• IEEE 802.3af Powered Device implementations
• Power management in LAN infrastructure equipment
• Embedded systems requiring PoE input

Procurement Notes

Verify the specific suffix 'PWR-1' against official Texas Instruments documentation to confirm exact marking and revision status. Ensure compatibility with target PCB footprint dimensions for the TSSOP-8 package. Confirm RoHS compliance details directly with the manufacturer or authorized distributors prior to final procurement decisions.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af specifications with integrated switching capabilities. The TSSOP-8 package suits space-constrained applications. Evaluate thermal performance requirements given the 1-ohm on-resistance and 405 mA current limit under expected load conditions.

Part Context

This part belongs to the Texas Instruments TPS2375 series of PoE controllers. It serves as a specialized solution for powering network devices via Ethernet cables. The series includes variants like the TPS2375DR and TPS2375PW, differing primarily in package type such as SOIC or TSSOP, while maintaining core functional similarities.

Replacement Considerations

The TPS2375DR is a pin-compatible alternative using an SOIC-8 package. Verify package dimensions and thermal characteristics before substitution.
