MAX5913AEMH

Hot Swap Controllers Overview

The MAX5913AEMH is a quad hot-swap controller designed for 48V applications, specifically supporting Power-over-LAN (PoL) and IEEE 802.3AF standards. It features four independent power switch controllers with an internal open-circuit detector and onboard charge pump. The device operates within a wide input voltage range of +35V to +72V and supports an operating temperature range from -40°C to +85°C. Packaged in a 44-pin MQFP (10x10mm) housing, it integrates protection mechanisms for safe insertion and removal of live circuits.

Hot Swap Controllers Feature Summary

• Four independent hot-swap channel controllers for simultaneous power distribution
• Integrated open-circuit detection capability for fault monitoring
• Onboard charge pump eliminates external bootstrap components
• Compatible with IEEE 802.3AF PoE standards

Hot Swap Controllers Applications

• Power-over-LAN (PoL) network infrastructure
• IP Phone power supply systems
• 48V distributed power architectures
• Telecommunications equipment hot-swap modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix (e.g., +D, +TD) against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the ordering part number matches the required temperature grade and RoHS compliance specifications. Cross-reference the component marking code with official Analog Devices documentation to prevent counterfeit substitution errors during assembly.

Hot Swap Controllers Selection Notes

Select this component when designing 4-channel 48V hot-swap interfaces requiring integrated fault detection. It is suitable for applications needing IEEE 802.3AF compliance without external charge pump circuitry. Consider the 44-MQFP footprint constraints and thermal dissipation requirements for dense PCB layouts in telecom or networking hardware designs.

Hot Swap Controllers Part Context

This device belongs to Maxim Integrated’s hot-swap controller family, engineered for robust power management in high-reliability environments. It addresses the need for safe module insertion in live 48V systems, commonly found in telecommunications and industrial networking gear. The quad-channel architecture simplifies multi-port power distribution design compared to single-channel alternatives.
