SI3462-E04-GM

Overview

The SI3462-E04-GM is a single-port Power Sourcing Equipment (PSE) interface controller compliant with IEEE 802.3at standards. It integrates a DC-DC controller and power switch for Gigabit Ethernet applications. The device operates within a supply voltage range of 2.7V to 3.6V and supports an operating temperature range of -40°C to 85°C. It is housed in a compact 11-QFN (3x3 mm) package with an exposed pad, designed for efficient power delivery over Ethernet cables.

Feature Summary

• Integrates PSE interface logic with a synchronous DC-DC controller for simplified design
• Supports IEEE 802.3at PoE+ power classification and detection protocols
• Includes integrated power switch for direct load connection

Applications

• Single-port PoE-powered devices requiring 802.3at compliance
• Gigabit Ethernet access points and wireless controllers
• IP cameras and networked security systems

Procurement Notes

Verify component authenticity through authorized Skyworks distributors. Confirm the specific suffix E04-GM matches project requirements. Check current availability status as supply may be limited. Ensure RoHS compliance documentation is available for regulatory adherence. Validate pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component for designs requiring a single-port 802.3at solution with integrated power switching. Compare against the SI3460 series if different interface requirements exist. Ensure the 11-QFN package fits the mechanical constraints. Verify that the 2.7V to 3.6V supply range aligns with the system power architecture.

Part Context

This part belongs to Skyworks' PoE/LAN solution family, specifically targeting single-port Ethernet interfaces. It complements other models like the SI3460 series by offering integrated power switching capabilities. The SI3462 series is designed to reduce component count and board space in modern networking equipment.

Replacement Considerations

The SI3462-E01-GM is listed as a potential substitute. Verify functional equivalence regarding the 802.3at standard and package compatibility. Confirm that the E01 variant meets the same electrical specifications and thermal requirements as the E04 version.
