MAX16055EAUB+T

Supervisors Overview

The MAX16055EAUB+T is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors six input voltages within a maximum supply range of 5.5 V, with a minimum operating voltage of 1 V. The device features adjustable threshold voltages ranging from 900 mV to 3.3 V and provides active low open-drain outputs. It includes a manual reset input and a reset delay time of 20 µs. The IC operates within a temperature range of -40°C to +125°C, consumes 25 µA to 55 µA in standby current, and dissipates up to 444 mW. It is housed in a UMAX-10 surface-mount package.

Supervisors Feature Summary

• Monitors up to six independent voltage rails simultaneously for system integrity
• Provides active low open-drain reset signals upon detecting undervoltage conditions
• Includes a manual reset input pin for external control over the reset state

Supervisors Applications

• Complex embedded systems requiring multi-rail power supervision
• Microprocessor-based boards needing precise voltage monitoring
• Industrial equipment with strict thermal operating requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the ordering suffix matches the reel packaging specification. Validate that the received part number corresponds exactly to the EAUB+T variant to avoid functional mismatches regarding threshold settings and package type.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage lines without watchdog timer functionality. The adjustable threshold range allows customization for various logic levels. Consider the UMAX-10 package size for space-constrained layouts. Verify that the 20 µs reset delay aligns with the target processor's startup timing requirements.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors. It shares the same core architecture as other variants like the MAX16055FAUB+T but differs in specific threshold configurations and packaging options. The series is designed for applications demanding high accuracy and low power consumption in compact form factors.
