LTC4266CGW#PBF

Overview

The LTC4266CGW#PBF is a four-channel Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af and 802.3at standards. It operates within a supply voltage range of 45V to 57V, drawing a typical supply current of 2.4mA. The device supports an operating temperature range from -40°C to +85°C and utilizes a 36-BSOP surface-mount package.

Feature Summary

• Supports simultaneous operation across multiple PoE and PoE+ classes
• Integrates Class detection logic for protocol compliance
• Provides per-channel power monitoring and protection

Applications

• Multi-port PoE injector modules
• PoE midspan power supplies
• Network infrastructure power distribution units

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with your system's thermal management requirements given the BSOP package. Confirm regulatory compliance status for your target market before finalizing procurement.

Selection Notes

Select this component when designing systems requiring independent control of four PoE ports. It is suitable for applications needing strict adherence to IEEE 802.3af/at standards. Consider the 36-BSOP package constraints for PCB layout and thermal dissipation during the design phase.

Part Context

This part belongs to the LTC4266 family of PSE controllers. It serves as a central management unit for powering remote devices over Ethernet cabling. It replaces discrete solutions by integrating detection, classification, and power delivery logic into a single IC.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any substitute maintains identical pin configurations and IEEE standard compliance.
