MAX16055AAUB+T

Supervisors Overview

The MAX16055AAUB+T is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors six independent supply voltages within the range of 900 mV to 3.3 V, including specific fixed thresholds of 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. The device operates with a maximum supply voltage of 5.5 V and features an active low, open-drain reset output. It includes manual reset functionality and maintains a reset delay time of 200 ms. The component supports surface mount installation in a UMAX-10 package and ensures high accuracy of 1.5% across an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors up to six distinct power supply rails simultaneously for system integrity
• Provides active low open-drain reset signal generation upon voltage fault detection
• Includes manual reset input capability for controlled system initialization

Supervisors Applications

• Complex embedded systems requiring multi-rail power supervision
• Industrial control units with multiple voltage domains
• Telecommunications equipment monitoring critical logic supplies

Supervisors Procurement Notes

Verify exact availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details directly with the manufacturer or authorized distributor before finalizing procurement plans. Ensure the ordering suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Supervisors Selection Notes

Select this component when simultaneous monitoring of six specific voltage levels is required within a compact footprint. The UMAX-10 package offers space efficiency for dense PCB layouts. Consider the 200 ms reset delay and 1.5% accuracy specifications against system timing requirements. Verify that the open-drain output interface aligns with the downstream processor's reset input logic requirements.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors designed for microprocessor applications. The family provides comprehensive power management oversight in minimal physical space. Variants within the series differ primarily in threshold configurations and packaging options, catering to diverse multi-voltage system architectures.

Supervisors Replacement Considerations

Cross-reference with other MAX16055 variants such as MAX16055FAUB+T or MAX16055IAUB+T if different threshold combinations are acceptable. Verify pinout compatibility and electrical parameter alignment before substituting.
