MAX5920AESA+

Hot Swap Controllers Overview

The MAX5920AESA+ is a single-channel hot-swap controller designed for -48V systems. It operates within a supply voltage range of -20V to -80V and functions between -40°C and +85°C. The device draws 700µA of quiescent current and dissipates up to 470mW. Packaged in an 8-pin SOIC, it integrates programmable circuit breaker, current limit, overvoltage protection (OVP), and undervoltage lockout (UVLO). Key features include fault timeout, latched fault handling, and thermal limiting capabilities.

• Features thermal limiting protection

Hot Swap Controllers Applications

• Telecom line cards
• Network switches and routers
• Central-office line cards
• Server line cards
• Base station line cards

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'A' indicates the qualified temperature grade and '+ denotes lead-free status. Request original manufacturer documentation to validate lot traceability and ensure compliance with RoHS standards before integration into production designs.

Hot Swap Controllers Selection Notes

Select this controller for -48V telecom environments requiring precise power sequencing and protection. Ensure external components match the required current limit and threshold settings. Verify that the SOIC-8 package fits the PCB layout constraints. Consider the 700µA quiescent current impact on system standby power budgets when evaluating alternative low-power options.

Hot Swap Controllers Part Context

Part of the Maxim Integrated hot-swap controller family, the MAX5920AESA+ addresses power distribution needs in telecommunications infrastructure. It complements other series members like the MAX5937 and MAX5939 by offering integrated protection without external sense resistors for basic configurations, though it supports external sensing for precision applications.
