MAX6933AAX+

Drivers, Receivers, Transceivers Overview

The MAX6933AAX+ is a dual-channel, high-voltage hot-swap controller manufactured by Analog Devices under the Maxim Integrated brand. Designed for safe insertion and removal of live circuit boards, it operates within an input voltage range of 4.5 V to 60 V. The device integrates adjustable current limiting with foldback protection and precise voltage monitoring capabilities. It utilizes a compact SSOP-28 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C. Key electrical specifications include a maximum supply current of 1.5 mA and configurable fault response mechanisms.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual-channel control for independent hot-swap management of separate power rails or loads.
• Provides programmable current limiting with foldback functionality to protect against short circuits during board insertion.
• Includes built-in voltage supervision features such as undervoltage lockout and overvoltage detection for system integrity.

Drivers, Receivers, Transceivers Applications

• Hot-pluggable peripheral cards in telecommunications infrastructure
• Server backplane power distribution modules
• Industrial control systems requiring safe module replacement

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AAX+' against the official Analog Devices datasheet to confirm pinout compatibility and thermal characteristics. Ensure the component source is authorized to avoid counterfeit risks, as this series is critical for power integrity. Cross-reference the manufacturing date code with project lifecycle requirements to ensure long-term availability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-channel isolation is required for hot-swap applications operating up to 60 V. Compare alternative single-channel controllers if only one rail requires protection. Evaluate the SSOP-28 footprint constraints against PCB layout space. Confirm that the internal gate drive strength meets the capacitance requirements of the target load switches.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX6933 family of hot-swap controllers, which are engineered for high-voltage server and telecom environments. The MAX6933 series provides robust protection for backplane systems, ensuring that live board insertion does not disrupt existing power rails or cause voltage transients that could damage connected electronics.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with legacy MAX6933 variants before substitution, as pinouts and electrical thresholds may differ between revisions.
