MAX5949BESA+T

Hot Swap Controllers Overview

The MAX5949BESA+T is a hot-swap voltage controller designed for -48V systems. It operates within a supply voltage range of -20V to -80V and supports an operating temperature range from -40°C to +85°C. The device features a power dissipation rating of 471 mW and utilizes an 8-SOIC surface-mount package. It provides comprehensive protection mechanisms including overvoltage protection, undervoltage lockout, fault timeouts, and automatic retry capabilities.

Hot Swap Controllers Feature Summary

• Integrated protection against overvoltage and undervoltage conditions with lockout functionality
• Supports automatic retry sequences following fault events
• Configurable fault timeout parameters for system safety

Hot Swap Controllers Applications

• -48V telecommunications infrastructure equipment
• Industrial control systems requiring hot-pluggable power modules
• Telecom base stations and network hardware

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and feature configuration. Ensure compatibility with -48V system architectures before integration. Cross-reference datasheet specifications for thermal management requirements given the 471 mW power dissipation limit in the SOIC-8 package.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust protection in negative voltage environments. Compare performance against the MAX5948 series if different protection thresholds or retry behaviors are required. Verify that the 8-SOIC package dimensions fit the target PCB layout constraints.

Hot Swap Controllers Part Context

This part belongs to the MAX5949 family of hot-swap controllers manufactured by Analog Devices (formerly Maxim Integrated). These devices are engineered for high-reliability applications where system availability and component protection during insertion or removal are critical. The family typically includes variants like the MAX5948 and MAX5949A/B.

Hot Swap Controllers Replacement Considerations

The MAX5948BESA+ is a related variant within the same product family. Verify functional equivalence regarding protection thresholds and control logic before substitution.
