TPS2383BPMG4

Overview

The TPS2383BPMG4 is an octal Power Sourcing Equipment (PSE) manager from Texas Instruments, compliant with IEEE 802.3af standards. It integrates control logic for eight independent PoE channels within a single 64-LQFP package. The device operates on supply voltages ranging from 3V to 3.6V and 44V to 57V, drawing a typical supply current of 5mA. It supports a maximum power output of 15.4W per channel. Designed for surface-mount installation, it functions within a commercial temperature range of 0°C to 70°C. The component is classified as a controller type without internal switches.

Feature Summary

• Supports eight independent PoE channels compliant with IEEE 802.3af standards
• Integrates comprehensive PSE management logic in a compact 64-LQFP package
• Operates with dual voltage domains for logic and power sourcing

Applications

• Octal PoE switch designs
• High-density network infrastructure equipment
• Power sourcing equipment controllers

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest documentation, as part numbers may have evolved or been superseded. Confirm availability status, as this component is listed as obsolete by major distributors. Ensure the 64-LQFP package dimensions match the target PCB footprint. Check RoHS compliance status for current manufacturing batches if sourcing from secondary markets.

Selection Notes

Select this component when designing systems requiring eight isolated PoE ports managed by a single controller IC. It is suitable for applications needing IEEE 802.3af compliance without integrating external switching transistors. Consider the 64-LQFP thermal performance and board space constraints. Verify that the system power budget aligns with the 15.4W maximum rating per channel.

Part Context

This part belongs to the TPS2383 family of octal PSE managers. It serves as a central control unit for powering remote devices over Ethernet cabling. The series is designed to simplify the implementation of multi-port PoE switches by handling classification, power allocation, and fault protection logic.
