MAX16055FAUB+

Supervisors Overview

The MAX16055FAUB+ is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features six monitored inputs with threshold voltages of 1.5 V, 2.5 V, 3.3 V, or adjustable settings. The device provides active low open-drain outputs and includes a manual reset function with a 200 ms reset delay time. It has no watchdog timer or battery backup switch. Operating current ranges from 25 uA to 55 uA, with an accuracy of 1.5%. The component is housed in a UMAX-10 package and functions reliably between -40 C and +125 C.

Supervisors Feature Summary

• Monitors six independent voltage rails simultaneously for system integrity
• Provides manual reset capability via dedicated control input
• Features low power consumption suitable for battery-operated applications
• Delivers active low open-drain status signals for logic interfacing

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Voltage supervision for complex multi-rail electronic circuits
• System reset generation in industrial control units
• Power management in portable consumer electronics

Supervisors Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold voltage selection and package type. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Ensure environmental compliance requirements match project specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage domains is required without watchdog functionality. The fixed threshold options simplify design compared to fully adjustable variants while maintaining precision. Consider the UMAX-10 package size constraints for PCB layout efficiency. Evaluate the 200 ms reset delay against system startup timing requirements to ensure proper initialization sequences are maintained during power-up events.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors designed for microprocessor applications. The family offers various threshold combinations and package options to suit different system architectures. Analog Devices acquired Maxim Integrated, integrating these legacy products into their broader portfolio. The series emphasizes compact footprint and low quiescent current for space-constrained designs.

Supervisors Replacement Considerations

Direct substitutes include other MAX16055 variants with different threshold configurations such as MAX16055GAUB+ or MAX16055AAUB+. Verify pin compatibility and electrical characteristics before substitution. No direct cross-brand replacements are documented in public sources.
