MAX16055GAUB+

Supervisors Overview

The MAX16055GAUB+ is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features six monitored inputs with threshold voltages of 2.5 V, 3.3 V, or adjustable settings. The device provides an active low, open-drain reset output with a fixed 200 ms reset delay time. It supports manual reset functionality and lacks watchdog timer or battery backup switch capabilities. Operating temperatures span from -40°C to +125°C, with accuracy specified at 1.5%. Quiescent current ranges from 25 µA to 55 µA, and 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 signal with configurable threshold options
• Supports manual reset input for controlled system initialization
• Operates reliably across extended industrial temperature ranges

Supervisors Applications

• Multi-rail power monitoring in embedded systems
• Microprocessor reset supervision in industrial controllers
• Voltage tracking in portable electronic devices
• System health monitoring in automotive electronics

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability prior to procurement. Check for obsolescence notices or lifecycle changes as availability may vary by region. Ensure packaging specifications match design requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this variant when six-channel voltage monitoring is required with specific 2.5 V or 3.3 V thresholds. Consider the UMAX-10 package for space-constrained designs. Verify that the 200 ms reset delay aligns with system startup timing requirements. Confirm compatibility with existing board layout constraints for the small outline package.

Supervisors Part Context

Part of the MAX16055 family of hex voltage supervisors designed for complex multi-voltage systems. Shares common architecture with variants offering different threshold combinations or additional features like watchdog timers. Designed to replace older single-channel supervisors in modern multi-rail architectures requiring consolidated monitoring solutions.

Supervisors Replacement Considerations

Cross-reference with MAX16055FAUB+ for adjustable threshold options or MAX16055HAUB+ for alternative threshold configurations. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official datasheets for functional equivalence confirmation.
