TPS2376D

Overview

The TPS2376D is a Powered Device 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 output power of 12.95 W. The device features a current limit of 405 mA and a maximum on-resistance of 1 Ohm. It functions reliably across an operating temperature range from -40°C to +85°C. The component draws a typical operating supply current of 240 uA and is housed in a SOIC-8 surface-mount package.

Feature Summary

• Complies with IEEE 802.3af standards for Powered Devices
• Integrates low on-resistance internal FET to reduce thermal losses
• Includes programmable current limiting with fault protection capabilities

Applications

• IP surveillance cameras
• Wireless access points
• VoIP telephones

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and thermal management needs. Confirm RoHS compliance status through manufacturer datasheets before integration into final assemblies.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af protocols. Consider the SOIC-8 footprint for space-constrained layouts. Evaluate thermal dissipation requirements based on the 1 Ohm on-resistance and 405 mA current limit when designing PCB copper pours.

Part Context

This part belongs to the TPS2376 series of PoE controllers manufactured by Texas Instruments. It serves as a foundational solution for implementing powered devices in network infrastructure. The series provides essential control logic and power switching capabilities required for standardized Ethernet power delivery systems.

Replacement Considerations

The TPS2376DR is a reel-manufactured variant of the same functional device. Verify package equivalence and ordering suffixes before substitution.
