MAX16055BAUB+

Supervisors Overview

The MAX16055BAUB+ 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 2.7 V to 5.5 V and monitors six independent input channels. The device features an active-low, open-drain reset output with a typical reset delay time of 200 ms. It supports manual reset functionality and lacks a watchdog timer or battery backup switch. The component is housed in a UMAX-10 surface-mount package and maintains accuracy within 1.5%. It functions reliably across an extended temperature range from -40°C to +125°C, with quiescent current consumption between 25 µA and 55 µA.

Supervisors Feature Summary

• Monitors six independent voltage rails for system integrity
• Provides active-low open-drain reset signal generation
• Supports manual reset input for system control
• Operates within extended industrial temperature ranges

Supervisors Applications

• Multi-rail power monitoring in embedded systems
• Microprocessor voltage supervision in industrial controllers
• System reset management in communication equipment

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure the UMAX-10 package footprint matches PCB design requirements. Validate threshold voltage specifications against target rail voltages to ensure proper supervision levels are met during operation.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in space-constrained designs. The UMAX-10 package offers a compact solution for hex supervision tasks. Consider the 200 ms reset delay and lack of watchdog features when designing timing-critical applications. Verify that the open-drain output interface aligns with the downstream logic requirements of the monitored system.

Supervisors Part Context

This part belongs to the MAX16055 series of ultra-small hex voltage supervisors. It shares the UMAX-10 package form factor with other variants like the FAUB+, GAUB+, and IAUB+. The series is designed for applications requiring multi-voltage monitoring in minimal board space. Different suffixes typically denote variations in threshold voltage settings or specific feature configurations within the same functional family.

Supervisors Replacement Considerations

Direct substitutes include MAX16055FAUB+, MAX16055GAUB+, and MAX16055IAUB+. Verify threshold voltage compatibility and pinout consistency before substitution. Check for any differences in reset delay times or operating current specifications between variants.
