MAX5934AEEE+T

Hot Swap Controllers Overview

The MAX5934AEEE+T is a positive high-voltage hot-swap controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of -80 V to -10 V and supports current limits up to 1 A. The device functions with a quiescent operating current of 1.4 mA and is rated for an extended industrial temperature range from -40°C to +85°C. Packaged in a surface-mount QSOP-16 format, this component is designed for robust power management applications requiring controlled insertion into live backplanes.

Hot Swap Controllers Feature Summary

• Provides precise control over voltage ramp-up during system insertion to prevent bus disturbances
• Integrates adjustable current limiting to protect against short circuits and overload conditions
• Includes fault protection mechanisms such as undervoltage lockout and timeout features

Hot Swap Controllers Applications

• Telecommunications equipment power systems
• Industrial control board power distribution
• Server and storage backplane power management

Hot Swap Controllers Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm that the QSOP-16 package matches your PCB footprint requirements. Ensure compatibility with negative voltage rails if used in standard telecom configurations. Check for RoHS compliance documentation before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when managing positive high-voltage inputs with strict insertion sequencing requirements. Consider the 1 A current limit capability relative to load demands. Evaluate the -80 V minimum supply rating against your system's maximum voltage spikes. The QSOP-16 package offers a compact solution for space-constrained designs compared to larger through-hole alternatives.

Hot Swap Controllers Part Context

This component belongs to the MAX5934 series of hot-swap controllers, which are engineered for reliable power delivery in critical infrastructure. It complements other Maxim Integrated PMICs by offering specialized protection for high-voltage environments. The device integrates essential safety features directly into a small form factor, reducing external component count.

Hot Swap Controllers FAQ
