Procurement Notes

Verify the End-of-Life status prior to procurement, as the manufacturer has announced discontinuation. Confirm that the 8-TSSOP package variant aligns with design requirements. Ensure compliance with humidity sensitivity handling procedures during storage and assembly. Check for available substitute part numbers if long-term supply stability is required for production.

Selection Notes

Select this component for designs requiring integrated IEEE 802.3af PoE-PD interface control with hot swap capabilities. Consider the 57 V maximum input voltage and 500 mA current limit when sizing external components. Evaluate the thermal performance within the specified -40°C to +85°C operating range. Verify compatibility with surface-mount assembly processes given the 8-TSSOP package type.

Part Context

The NCP1092DBRG belongs to onsemi's NCP109x series of high-power HIPO PoE-PD products. This family integrates interface controllers compliant with IEEE 802.3af standards. The DBRG suffix indicates the 8-TSSOP package configuration. Related models include NCP1090 and NCP1091, which offer similar functionalities in different package options or pin configurations.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data. Due to the End-of-Life status, verify alternative solutions directly with the manufacturer or authorized distributors.
