TPS2375DRG4

Overview

The TPS2375DRG4 is a single-channel IEEE 802.3af-compliant Powered Device (PD) controller 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 a maximum output power of 12.95 W. It functions across an extended temperature range from -40°C to +85°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Complies with IEEE 802.3af standards for Powered Device classification and control
• Integrates an internal N-channel power switch for compact design
• Includes built-in protection mechanisms against overcurrent and thermal events

Applications

• IEEE 802.3af compliant network endpoints
• VoIP telephones
• Wireless LAN access points
• Network surveillance cameras

Procurement Notes

Verify the suffix 'G4' indicates lead-free construction and RoHS compliance during procurement. Confirm the package designation matches the 8-SOIC form factor required for the target PCB layout. Ensure the component status remains active as it is listed as a standard product in official catalogs.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af specifications with minimal external component count. The integrated switch eliminates the need for discrete MOSFETs, reducing board space. Verify that the 405 mA current limit and 12.95 W power budget align with the specific load requirements of the application.

Part Context

This part belongs to the TPS2375 family of PoE controllers designed for low-power network devices. It serves as a direct replacement for non-green variants within the same series, maintaining identical electrical performance while adhering to environmental directives. The DRG4 suffix specifically denotes the tape-and-reel packaging format compatible with automated assembly lines.

Replacement Considerations

The TPS2375DR is the non-green equivalent counterpart. Other members of the TPS2375 family may offer different pinouts or packages but require verification of functional compatibility before substitution.
