NCP1093MNRG

Overview

The NCP1093MNRG is a Power over Ethernet (PoE) controller designed for Powered Device (PD) applications, compliant with IEEE 802.3af and 802.3at standards. It operates within a supply voltage range of 0V to 57V and supports a maximum power output of 25.5W. The component integrates internal switches and features a single channel configuration. It is housed in a 10-DFN (3x3mm) package with an exposed pad for thermal management. The device functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Compliant with IEEE 802.3af and 802.3at PoE standards
• Integrates internal power switches for simplified design
• Supports hot-swap operations for powered devices

Applications

• IEEE 802.3af Powered Devices
• IEEE 802.3at Powered Devices
• Network infrastructure equipment

Procurement Notes

Verify the obsolete status indicated by the March 2024 Product Change Notification before finalizing designs. Confirm that the 10-DFN package dimensions align with current PCB layout requirements. Ensure compliance with RoHS3 specifications and MSL Level 3 moisture sensitivity ratings during assembly planning.

Selection Notes

Select this component for single-channel PoE PD implementations requiring integrated switching capabilities. Consider the 10-DFN footprint constraints and thermal dissipation needs associated with the 25.5W power limit. Evaluate compatibility with existing IEEE 802.3af/at network architectures.

Part Context

Part of onsemi's HIPO series, the NCP1093MNRG serves as a dedicated controller for PoE applications. It replaces older discrete solutions by integrating control logic and power stages into a compact form factor, facilitating efficient power delivery over Ethernet cabling.
