MAX16055DAUB+T

Supervisors Overview

The MAX16055DAUB+T is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors six independent power supply rails within a compact UMAX-10 surface-mount package. The device supports a maximum supply voltage of 5.5 V and operates with a quiescent current ranging from 25 uA to 55 uA. Threshold voltages are adjustable between 900 mV and 3.3 V, providing flexibility for various logic levels. It features a manual reset input and an active-low open-drain output. The reset delay time is specified at 20 us, ensuring rapid response to voltage anomalies.

Supervisors Feature Summary

• Monitors up to six independent voltage inputs simultaneously
• Features adjustable threshold detection capabilities
• Includes manual reset functionality for system control
• Provides active-low open-drain status output

Supervisors Applications

• Complex embedded systems requiring multi-rail power supervision
• Industrial control units with multiple voltage domains
• Telecommunications equipment power management
• Portable electronic devices needing low-power monitoring

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold settings and packaging type. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check RoHS compliance documentation for regulatory adherence in target markets.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in space-constrained designs. The adjustable thresholds allow customization for diverse logic families without external resistors. Consider the low quiescent current for battery-operated applications. Ensure the UMAX-10 package fits the PCB footprint constraints and thermal requirements of the final assembly.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors. The series is designed for complex systems where multiple power supplies must be tracked reliably. The DAUB variant specifically denotes the adjustable threshold configuration within the UMAX-10 package format, distinguishing it from fixed-threshold counterparts in the same family.

Supervisors Replacement Considerations

Check for MAX16055GAUB+ or MAX16055EAUB+ if fixed thresholds suffice. Verify pin compatibility before substitution. Review datasheet differences in reset timing and accuracy specifications.
