TPS2383PM

Overview

The TPS2383PM is an eight-channel Power Sourcing Equipment (PSE) controller compliant with the IEEE 802.3af standard. It operates within a supply voltage range of 3V to 3.6V for logic and 44V to 57V for power, drawing a typical supply current of 5mA. The device supports a maximum power output of 15.4W per channel and functions without internal switches. It is housed in a 64-LQFP package measuring 10x10mm and is rated for operation between 0°C and 70°C.

Feature Summary

• Provides centralized management for up to eight PoE channels
• Ensures compliance with IEEE 802.3af classification protocols
• Integrates hot-swap control for safe power application

Applications

• Centralized Power Sourcing Equipment (PSE) systems
• Multi-port Ethernet switch designs requiring PoE support
• Network infrastructure powering endpoints via LAN cables

Procurement Notes

Verify component status as this part may be discontinued. Confirm package availability and lead times through authorized distributors. Ensure RoHS compliance matches project requirements. Check for obsolescence notices from Texas Instruments before finalizing design-in decisions.

Selection Notes

Select this controller for applications requiring multiple PoE ports managed by a single IC. It suits designs needing 802.3af compliance without integrated high-side switches. Consider thermal management for the LQFP package. Evaluate system power budget against the 15.4W per channel limit.

Part Context

This component belongs to the Texas Instruments TPS2383 family of PoE controllers. It serves as a central management unit for multi-port PSE implementations. The device simplifies design by handling classification and power sequencing externally.

Replacement Considerations

Check for direct pin-compatible upgrades or newer generations within the TPS238x series. Verify functional equivalence for 802.3af compliance if substituting.
