Overview
The TPS2384APJDR is a quad integrated Power Sourcing Equipment (PSE) power manager from Texas Instruments, compliant with IEEE 802.3af standards. It integrates four independent channels for PoE applications. Key electrical parameters include a maximum current limit of 450 mA per channel and a maximum on-resistance of 1.8 ohms. The device operates at a supply voltage of 48 V and functions within a temperature range of -40°C to +125°C. It is housed in an HTQFP-64 surface-mount package.
Feature Summary
- Integrates four independent power sourcing equipment channels for quad Ethernet applications
- Complies with IEEE 802.3af standards for Power over Ethernet
- Includes built-in protection features such as current limiting
Applications
- Quad port Power over Ethernet switches
- IEEE 802.3af compliant network infrastructure
- Ethernet-powered device management systems
Procurement Notes
Verify the specific suffix 'PJDR' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the HTQFP-64 package. Confirm that the 450 mA current limit meets your downstream load requirements. Check for any updated revision notes or pin-to-pin alternatives in the latest product selection guide.
Selection Notes
Select this component when designing quad-channel PoE solutions requiring IEEE 802.3af compliance. The integrated nature reduces external component count compared to discrete designs. Consider the 1.8 ohm on-resistance for thermal management calculations. Verify that the operating temperature range suits your environmental conditions. This part is suitable for high-density Ethernet switch designs.
Part Context
The TPS2384 series represents Texas Instruments' portfolio of integrated PSE managers. The TPS2384APJDR specifically addresses the need for multi-port PoE distribution in compact form factors. It simplifies design by combining control logic, protection, and switching elements into a single IC, reducing board space and complexity for network equipment manufacturers.
Replacement Considerations
Consult the Texas Instruments official documentation for verified pin-compatible or functionally equivalent alternatives. Cross-reference with other members of the TPS238x family if different channel counts or performance metrics are required.
