Procurement Notes

Verify current availability status as components may be discontinued or subject to long lead times. Confirm exact ordering suffixes match design requirements. Check for recommended replacement parts from the manufacturer if original stock is unavailable. Ensure RoHS compliance documentation is available for regulatory adherence.

Selection Notes

Select this controller for designs requiring standardized PoE PD implementation. Ensure input voltage ranges align with network switch capabilities. Verify thermal management requirements for the LQFP package in enclosed environments. Consider channel count needs against available pin configurations.

Part Context

This part belongs to the TPS2383 family of PoE controllers designed for compliant powered device implementations. It integrates necessary control circuitry to negotiate power with PSE switches. The PMRG4 suffix indicates specific packaging and environmental compliance attributes defined by Texas Instruments for mass production.

Replacement Considerations

TPS2383BPMR is listed as a manufacturer-recommended alternative. Verify functional compatibility and pinout equivalence before substitution. Review updated datasheets for any parameter differences between variants.
