MAX16055JAUB+

Supervisors Overview

The MAX16055JAUB+ is a hex voltage microprocessor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors six independent supply voltages and provides active-low reset signals via open-drain outputs when thresholds are violated. The device operates within a supply voltage range of 1V to 5.5V, featuring a manual reset input and a typical reset delay time of 20µs. It supports adjustable threshold voltages from 900mV to 3.3V with an accuracy of 1.5%. Packaged in a compact UMAX-10 surface-mount case, it functions reliably across an extended temperature range of -40°C to +125°C while consuming low quiescent current.

Supervisors Feature Summary

• Monitors up to six independent power supply rails simultaneously
• Provides active-low open-drain reset outputs for system protection
• Supports manual reset input for controlled system initialization
• Operates with low quiescent current in a compact UMAX-10 package

Supervisors Applications

• Portable battery-powered equipment requiring multi-rail supervision
• Embedded systems needing reliable power-fail detection
• Industrial control units operating in extreme temperatures
• Communication infrastructure monitoring critical voltage levels

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this specific part number may be discontinued. Ensure the UMAX-10 package matches your PCB footprint requirements before finalizing orders.

Supervisors Selection Notes

Select this supervisor for applications requiring simultaneous monitoring of multiple voltage rails without watchdog timer functionality. Consider the 20µs reset delay and open-drain output configuration for compatibility with downstream logic. Verify that the adjustable threshold range covers all required supply voltages within the 1V to 5.5V operational window.

Supervisors Part Context

This component belongs to the MAX16055 series of ultra-small hex voltage supervisors designed for complex system monitoring. It integrates multiple voltage comparators into a single compact package, eliminating the need for discrete monitoring solutions. The series is optimized for space-constrained designs requiring high reliability and precise voltage tracking across various industrial and consumer electronics applications.
