MAX5911ESA

Hot Swap Controllers Overview

The MAX5911ESA is a hot-swap controller designed for -48V systems, featuring an internal high-side switch and integrated current sensing. It supports supply voltages from -65V to -16V with a maximum output current of 280mA. The device operates within a temperature range of -40°C to 85°C and draws 1.5mA of supply current. Key programmable features include under-voltage lockout (UVLO) and thermal limiting protection.

Hot Swap Controllers Feature Summary

• Integrates a high-side power switch with built-in current sensing capabilities
• Provides thermal limiting protection to prevent overheating during operation
• Supports programmable under-voltage lockout for system stability

Hot Swap Controllers Applications

• Safe insertion and removal of circuit boards in live backplanes
• -48V telecommunications and networking equipment
• Protection against overcurrent conditions and short circuits

Hot Swap Controllers Procurement Notes

Verify the specific suffix (+ or +T) to confirm lead-free status and tape-and-reel packaging requirements. Ensure the component matches the 8-SOIC package dimensions. Confirm that the -48V application aligns with the specified -65V to -16V supply voltage range. Check for active part status and availability through authorized Analog Devices distributors.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise board insertion management in -48V environments. The internal switch eliminates external MOSFETs, simplifying design. Consider the 8-SOIC package for surface-mount assembly. Verify that the 280mA output current meets load requirements and that UVLO settings match system power sequencing needs.

Hot Swap Controllers Part Context

This component belongs to the MAX5911 family of hot-swap controllers manufactured by Maxim Integrated, now part of Analog Devices. These devices are engineered for high-voltage, high-side switching applications where safe board handling is critical. The ESA variant specifically denotes the standard industrial temperature range and SOIC package configuration.

Hot Swap Controllers Replacement Considerations

Consult official Analog Devices documentation for direct pin-to-pin replacements. Verify compatibility with -48V systems and ensure equivalent thermal and current protection features. Cross-reference package dimensions and electrical specifications before substitution.
