MAX16055FAUB+T

Supervisors Overview

The MAX16055FAUB+T is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors six input voltages within a range of 900 mV to 3.3 V using a UMAX-10 surface-mount package. The device features an active low, open-drain output and supports manual reset functionality without a watchdog timer or battery backup switch. It operates on supply voltages up to 5.5 V with a typical quiescent current between 25 uA and 55 uA. The reset delay time is specified at 20 us, and the unit functions reliably across an industrial temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Monitors multiple system voltages simultaneously for reliable power supervision
• Provides manual reset capability for controlled system recovery
• Utilizes ultra-small packaging for space-constrained board layouts

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Voltage supervision for complex digital logic circuits
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance details and check for obsolescence notices before finalizing procurement plans. Ensure storage conditions meet moisture sensitivity level requirements to maintain device integrity during assembly processes.

Supervisors Selection Notes

Select this component when simultaneous monitoring of six distinct voltage rails is required within a compact footprint. Consider the specific threshold voltage options available for the FA variant against system requirements. Evaluate the trade-off between the fast 20 us reset delay and the absence of watchdog features for your specific application stability needs.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors designed for demanding portable applications. It shares the same core architecture as other variants in the family but differs in specific threshold configurations and packaging suffixes. The series emphasizes low power consumption and high accuracy for critical system protection tasks.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX16055 family such as MAX16055EAUB+T or MAX16055IAUB+ if sourcing constraints exist. Verify that any substitute maintains identical threshold specifications and package dimensions to ensure seamless integration without redesigning the host PCB layout.
