MAX5914AEMH+

Hot Swap Controllers Overview

The MAX5914AEMH+ is a quad hot-swap controller designed for high-voltage applications, supporting up to 48V input. It integrates four independent channels with adjustable current limits and delay times. The device features an active-high relay driver output capable of sourcing 1mA to drive external FETs. It operates within a temperature range of -40°C to +85°C and is housed in a 44-MQFP (10x10) package.

Hot Swap Controllers Feature Summary

• Integrates four independent hot-swap control channels for simultaneous power management
• Supports high-voltage operation up to 48V for telecom and industrial systems
• Includes an active-high relay driver output to interface with external FET drivers
• Provides adjustable current limiting and soft-start timing for controlled power-up

Hot Swap Controllers Applications

• Telecommunications equipment power distribution
• Power over LAN (PoE) infrastructure controllers
• Industrial system backplane power management
• High-voltage server and storage array hot-plug modules

Hot Swap Controllers Procurement Notes

Verify the exact suffix designation (+ or -D) against the manufacturer's official datasheet to ensure correct pinout and electrical specifications. Confirm RoHS compliance status directly with Analog Devices or authorized distributors, as packaging variations may exist. Ensure the 44-MQFP footprint matches the target PCB design before procurement.

Hot Swap Controllers Selection Notes

Select this component when multiple independent hot-swap channels are required within a single IC footprint. It is suitable for designs needing 48V tolerance and precise current limiting per channel. Consider the MQFP package size constraints and thermal requirements for the specific application environment.

Hot Swap Controllers Part Context

This part belongs to the MAX5914 family of quad hot-swap controllers from Maxim Integrated, now part of Analog Devices. These devices are engineered for robust power management in high-density electronic systems, offering integrated protection features typically requiring discrete components in older designs.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers include MAX5914AEMH+TD and MAX5914AEMH-T. Verify pin compatibility and electrical parameters before substitution.
