NCP1081DER2G

Overview

The NCP1081DER2G is an integrated high-power Power over Ethernet (PoE) Powered Device (PD) interface and DC-DC converter controller from onsemi. It supports IEEE 802.3at/af standards and draft IEEE 802.3bt, enabling extended power ranges up to 40 W. The device features a built-in Low Dropout Regulator (LDO), programmable classification, and comprehensive protection mechanisms including undervoltage and thermal protection. Packaged in a TSSOP-20 surface-mount format, it provides PGOOD status indication for system monitoring.

Feature Summary

Integrated PoE-PD interface with DC-DC converter control
Supports IEEE 802.3at/af and draft 802.3bt standards
Built-in LDO and PGOOD status indication
Includes undervoltage and thermal protection

Applications

High-power PoE-powered devices
Industrial automation controllers
Wireless access points requiring extended power

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Review the Product Discontinuance Notification for lifecycle management strategies. Ensure supply chain stability as availability may be restricted.

Selection Notes

Select this component for designs requiring integrated PoE PD and DC-DC conversion in a compact form factor. Consider the TSSOP-20 package constraints and thermal performance requirements. Evaluate compatibility with IEEE 802.3bt draft specifications if higher power delivery is needed.

Part Context

This part belongs to onsemi's HIPO series of high-power Power over Ethernet controllers. It is designed to simplify the implementation of high-power PoE applications by combining interface logic and power conversion control into a single IC, reducing bill of materials count.

Replacement Considerations

The NCP1082DER2G is a related model within the same family but supports different power classifications. Verify functional equivalence regarding pinout and control logic before substitution.
