TPS2375DR

Overview

The TPS2375DR is a Texas Instruments power switch IC designed for IEEE 802.3af Powered Devices (PD). It integrates a high-voltage power switch and control logic to manage Power over Ethernet connections. The device operates within a voltage range of 0 V to 57 V and supports a maximum current limit of 405 mA. It features a maximum on-resistance of 1 ohm and delivers up to 12.95 W of output power. The component is housed in an 8-SOIC surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-voltage power switch with dedicated control logic for seamless Powered Device implementation
• Provides comprehensive protection mechanisms including thermal shutdown and fault response capabilities
• Supports standard IEEE 802.3af classification for automatic power negotiation and management

Applications

• IEEE 802.3af Powered Device implementations
• Power over Ethernet interface circuits
• LAN powered equipment controllers

Procurement Notes

Verify the specific ordering suffix 'R' confirms the tape-and-reel packaging configuration distinct from tube variants. Ensure the component matches the 8-SOIC physical footprint and electrical specifications required for the target design. Confirm RoHS compliance status aligns with environmental regulations for the intended market. Cross-reference the manufacturer part number against official datasheets to validate revision levels before integration.

Selection Notes

Select this component when designing for IEEE 802.3af standards requiring integrated switching and control. Consider the 8-SOIC package constraints for board space limitations. Evaluate the 405 mA current limit and 12.95 W power capability against load requirements. Assess the operating temperature range suitability for the deployment environment compared to higher-temperature alternatives.

Part Context

The TPS2375DR belongs to the TPS2375 series of power switch ICs from Texas Instruments. This family focuses on simplifying Powered Device designs by combining power switching and control functions. The DR suffix specifically denotes the reel-packaged version of the SOIC-8 variant, distinguishing it from other packaging options within the same functional family.
