MAX16055AAUB+

Supervisors Overview

The MAX16055AAUB+ is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors six independent input voltages within a supply range of 1V to 5.5V. The device features fixed threshold options including 900mV, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. It provides an active-low open-drain reset output with a standard 200ms reset delay time. The component operates reliably across an extended temperature range from -40°C to +125°C. It draws a low quiescent current between 25µA and 55µA and is housed in a compact 10-UMAX surface-mount package.

Supervisors Feature Summary

• Monitors up to six independent voltage rails simultaneously for comprehensive system supervision
• Provides manual reset capability via dedicated input pin for controlled system recovery
• Delivers active-low open-drain reset signal with configurable threshold voltages
• Operates at ultra-low quiescent current suitable for battery-powered applications

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor and FPGA voltage supervision
• Industrial control board power integrity verification
• Communication equipment power rail validation

Supervisors Procurement Notes

Verify exact availability through authorized distributors as stock levels fluctuate. Confirm RoHS compliance status and lead times prior to ordering. Ensure the specific suffix matches required threshold configurations. Check for obsolescence notices or lifecycle changes directly with the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this part when simultaneous monitoring of multiple voltage rails is required without watchdog functionality. Choose based on specific threshold requirements among available fixed options. Consider the UMAX-10 package size for space-constrained designs. Verify that the 200ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This component belongs to the MAX16055 series of hex voltage supervisors designed for complex digital systems. It serves as a critical reliability element in multi-voltage architectures where precise monitoring of individual rails is essential. The series offers various threshold combinations to accommodate different logic families and power standards commonly found in modern electronic designs.

Supervisors Replacement Considerations

Cross-reference with other MAX16055 variants such as EAUB+, GAUB+, or HAUB+ for different threshold configurations. Verify package compatibility and electrical parameter alignment when substituting. No direct equivalent substitutes are publicly confirmed for this specific part number.
