Overview
The TPS2375DG4 is an IEEE 802.3af PoE Powered Device Controller manufactured by Texas Instruments in a TSSOP-8 package. 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 a temperature range of -40°C to +85°C.
Feature Summary
- Complies with IEEE 802.3af standards for Power over Ethernet powered devices
- Integrates a true open-drain power-good function for system status indication
- Features high-voltage ratings suitable for robust PoE interface applications
Applications
- IEEE 802.3af compliant network endpoint devices
- PoE-powered surveillance cameras and access points
- Industrial control systems requiring isolated power interfaces
Procurement Notes
Verify the specific suffix 'DG4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOIC-8 or TSSOP-8 package designation matches your PCB footprint requirements. Ensure the operating voltage and current limits align with your downstream DC-DC converter specifications before finalizing procurement.
Selection Notes
Select this component when designing systems strictly adhering to the IEEE 802.3af standard. It is appropriate for applications requiring a dedicated PD controller without integrated DC-DC conversion, unlike the TPS23751/2 series. Consider the 405 mA current limit and 1 ohm on-resistance for power budget calculations.
Part Context
This part belongs to the TPS2375 family of second-generation PoE controllers. It serves as a foundational interface component for powering network devices via Ethernet cables. Unlike integrated solutions, it focuses on detection, classification, and protection logic for the powered device side of the link.
Replacement Considerations
The TPS2375D is the non-compliant predecessor. For RoHS-compliant alternatives within the same family, verify availability of TPS2375PWR. Note that the TPS23751 and TPS23752 include integrated DC-DC controllers and are not direct pin-compatible replacements.
