Frequently Asked Questions
What IEEE standard does the TPS2376DG4 support for Power over Ethernet?
The TPS2376DG4 fully complies with the IEEE 802.3af standard for Power over Ethernet, which defines the protocol for delivering up to 15.4W of DC power over standard Cat5 or Cat5e Ethernet cables. It implements all required powered device (PD) functions including detection, classification, and inrush current management, ensuring interoperability with IEEE 802.3af-compliant Power Sourcing Equipment (PSE) from any manufacturer.
What functions does the TPS2376DG4 integrate on-chip?
The TPS2376DG4 integrates the complete IEEE 802.3af powered device (PD) controller function in a single IC, including detection signature resistor emulation (25kΩ), power classification current source for Class 1-4 classification, inrush current limiting during capacitor charging, and soft-start power-up control. This high level of integration eliminates multiple discrete components from the PoE front-end circuit, reducing BOM cost and simplifying PCB design.
What is the package type and pin count of the TPS2376DG4?
The TPS2376DG4 is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with a 3.9mm body width and 1.27mm pin pitch, as indicated by the JESD-30 code R-PDSO-G8. The compact SOIC-8 package is well suited for PoE-powered devices where PCB space is at a premium, such as dome cameras and compact wireless access points. The G4 suffix identifies the RoHS-compliant lead-free version.
Can the TPS2376DG4 be used with both alternative-A and alternative-B PoE power delivery?
Yes, the TPS2376DG4 is designed to support both PoE power delivery modes defined in IEEE 802.3af. Alternative A delivers power over the data pairs (pins 1, 2, 3, 6), while Alternative B uses the spare pairs (pins 4, 5, 7, 8). The device manages detection and classification signaling independently of the power pair configuration, enabling flexible PCB design for PoE-powered endpoints compatible with any compliant PSE switch or injector.
Is the TPS2376DG4 still in production and what is its end-of-life status?
Based on available product information, the TPS2376DG4 has a YTEOL (Years To End Of Life) value of 0, which may indicate it is approaching or at end-of-life status. Designers starting new projects should consult the Texas Instruments product page for the current lifecycle status and consider evaluating newer PoE PD controller alternatives such as the TPS2376-Q1 or other active TI PoE solutions to ensure long-term supply availability.
