SI3460-E02-GM

Overview

The SI3460-E02-GM is a single-port Power over Ethernet (PoE) Powered Device (PD) interface controller compliant with the IEEE 802.3af standard. It integrates a DC-DC controller to manage power delivery for downstream loads. The device operates within a supply voltage range of 44 V to 57 V and supports a maximum current limit of 680 mA. Designed for surface-mount installation, it utilizes an 11-QFN package measuring 3x3 mm. The component functions as a complete solution for PoE applications, combining classification, switch control, and power conversion management in a compact form factor suitable for space-constrained network equipment.

Feature Summary

• Integrates IEEE 802.3af compliant PD interface with built-in DC-DC controller
• Provides auxiliary sense capability for enhanced power regulation accuracy
• Supports single-channel operation for dedicated powered device applications

Applications

• IP cameras and video surveillance systems
• Wireless access points and network infrastructure
• VoIP telephones and communication endpoints

Procurement Notes

Verify component authenticity through authorized Skyworks distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during soldering processes.

Selection Notes

Select this component for designs requiring strict adherence to 802.3af standards with integrated power conversion. Evaluate thermal performance within the 3x3 mm QFN footprint against system heat dissipation capabilities. Compare current limits and input voltage ranges against specific load requirements to ensure operational stability.
