SI3454-B01-IM

Overview

The SI3454-B01-IM is a Power Over Ethernet (PoE) controller designed for IEEE 802.3at compliant systems. It functions as a four-port Powered Device (PD) controller, managing power negotiation and delivery across multiple Ethernet interfaces. The component integrates the necessary logic to handle Class 4 PD operations, ensuring compatibility with standard PoE infrastructure while providing robust control over power states and fault conditions.

Feature Summary

• Supports four independent Ethernet ports for simultaneous PoE operation
• Complies with IEEE 802.3at standards for advanced power delivery
• Integrates complete Powered Device control logic

Applications

• Four-port PoE Powered Devices
• IEEE 802.3at compliant network endpoints
• Multi-interface PoE controllers

Procurement Notes

Verify component status before procurement as it is marked Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that lead times may vary significantly due to production constraints. Ensure design-in decisions account for potential obsolescence risks associated with this lifecycle stage.

Selection Notes

Select this component for designs requiring integrated four-port PoE PD control under IEEE 802.3at specifications. Evaluate suitability carefully given its NRND status, which suggests limited long-term supply assurance. Consider alternative newer generation controllers if future-proofing is required for mass production volumes.
