TPS2383BPM

Overview

The TPS2383BPM is an octal Power Sourcing Equipment (PSE) manager manufactured by Texas Instruments. It supports the IEEE 802.3af PoE standard and provides control for eight independent channels. The device operates with a supply voltage range of 3V to 3.6V and handles port voltages between 44V and 57V. It features a maximum power output of 15.4 W per channel and does not include internal switches. The component is housed in a 64-LQFP package measuring 10x10 mm and is rated for operation within a temperature range of 0°C to 70°C.

Feature Summary

• Manages up to eight PoE ports compliant with IEEE 802.3af standards
• Provides precise voltage regulation and current limiting for powered devices
• Integrates thermal protection and fault monitoring capabilities

Applications

• Octal PoE switch designs
• Power over Ethernet midspan injectors
• Network infrastructure equipment requiring multi-port power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels, as the TPS2383BPM is officially listed as obsolete. Confirm that replacement inventory meets RoHS3 compliance requirements and matches the specified 64-LQFP package dimensions. Ensure storage conditions adhere to moisture sensitivity level 3 guidelines to prevent damage prior to assembly.

Selection Notes

Select this controller for applications requiring centralized management of multiple PoE endpoints without integrated switching elements. Consider the absence of internal switches when designing board layouts, as external MOSFETs are required for each channel. Evaluate the 64-LQFP footprint against available PCB space and thermal dissipation constraints for high-density deployments.

Part Context

This component belongs to the TPS2383 family of octal PSE managers designed for network communication systems. It serves as a central control unit for distributing power over Ethernet cables while maintaining protocol compliance. The device simplifies system design by handling detection, classification, and power delivery sequencing for connected endpoints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the TPS2383BPM is marked obsolete, engineers must evaluate alternative octal PSE controllers from current product lines or redesign using discrete components to maintain system functionality.
