MAX5935CAX+T

Overview

The MAX5935CAX+T is a Power over Ethernet (PoE) controller designed for 802.3af compliant systems. It supports four channels and operates with a supply voltage range of 32V to 60V. The device integrates control logic for managing power delivery, featuring a typical supply current of 4.2mA. It is housed in a 36-SSOP package, providing a compact solution for PoE applications requiring multi-channel management.

Feature Summary

• Supports 802.3af (PoE) standards
• Integrates four independent control channels
• Operates within a wide input voltage range

Applications

• Power over Ethernet controllers
• Multi-channel PoE power management systems
• Network infrastructure equipment

Procurement Notes

Verify the component lifecycle status as sources indicate it may be obsolete. Confirm the package type is 36-SSOP or BSOP as listed in various catalogs. Ensure compatibility with 802.3af requirements before procurement. Check for lead times due to limited availability mentioned in some distributor listings.

Selection Notes

Select this component for designs requiring integrated control for up to four PoE ports under the 802.3af standard. Consider the 32V to 60V operating range for power supply design. Evaluate the 36-pin SSOP footprint for PCB layout constraints. Compare against newer alternatives if long-term supply assurance is critical.
