TPS2376PWRG4

Overview

The TPS2376PWRG4 is a Powered Device (PD) controller compliant with the IEEE 802.3af standard, designed for Power over Ethernet applications. It operates within a supply voltage range of 0 V to 57 V and supports a maximum current limit of 405 mA. The device features a maximum on-resistance of 1 ohm and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a TSSOP-8 surface-mount format, it integrates essential control logic for PoE power delivery.

Feature Summary

• Complies with IEEE 802.3af standards for powered devices
• Integrates high-voltage protection capabilities
• Supports low-power operation modes

Applications

• IP surveillance cameras
• Wireless access points
• VoIP telephones

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package designation matches the required TSSOP-8 footprint for PCB layout compatibility. Ensure the component meets the intended environmental temperature ratings for the final assembly. Cross-reference the ordering part number with official Texas Instruments databases to validate availability and revision levels before procurement.

Selection Notes

Select this component for designs requiring strict adherence to the IEEE 802.3af PoE specification. The integrated controller simplifies design by reducing external component count compared to discrete solutions. Consider the 405 mA current limit when sizing downstream power stages. The TSSOP-8 package offers a compact solution for space-constrained embedded networking hardware.

Part Context

This device belongs to the TPS2376 family of PoE controllers manufactured by Texas Instruments. It serves as a core interface between the Ethernet physical layer and the local power bus. The family includes variants such as the TPS2376DDAR-H for higher power applications. These controllers are widely used in industrial and commercial networking infrastructure.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter alignment with existing designs.
