MAX6826MUT+

Supervisors Overview

The MAX6826MUT+ is a dual micro-power voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent input voltages and provides active-low push-pull outputs for undervoltage conditions. The device features adjustable threshold voltages ranging from 900 mV to 2.5 V for one channel and 1.8 V to 5 V for the other, with an overvoltage threshold of 1.629 V. It includes a manual reset function and a watchdog timer. Operating within a supply voltage range up to 5.5 V, it draws only 10 uA of quiescent current. The component supports a reset delay time of 320 ms and operates reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Dual-channel voltage supervision with independent adjustable thresholds
• Integrated manual reset capability and watchdog timer functionality
• Ultra-low power consumption suitable for battery-operated systems
• Active-low push-pull output configuration for direct logic interfacing

Supervisors Applications

• Portable electronic devices requiring multi-voltage monitoring
• Battery-powered equipment needing low standby current
• Industrial control systems utilizing extended temperature ranges
• Automotive electronics compliant with harsh environment standards

Supervisors Procurement Notes

Verify the specific suffix 'MUT+' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution channels may indicate limited stock or discontinuation phases. Ensure the ordering part number matches the required threshold configurations and thermal performance ratings for your specific application design constraints.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in a compact surface-mount package. Consider the adjustable threshold ranges to ensure compatibility with system rail voltages. Evaluate the 10 uA quiescent current against total system power budgets. Verify that the 320 ms reset delay meets the timing requirements of the controlled circuitry during power-up sequences.

Supervisors Part Context

The MAX6826 belongs to Maxim Integrated's family of micro-power supervisors designed for space-constrained applications. It integrates dual supervisory circuits into a single SOT-23-6 package, reducing board area compared to discrete solutions. This series emphasizes low power consumption and high accuracy, making it suitable for modern portable and industrial electronics where efficiency and reliability are critical design parameters.

Supervisors Replacement Considerations

Consult official cross-reference guides for equivalent dual-supervisor ICs with similar threshold adjustability and package dimensions. Verify pinout compatibility before substitution to prevent circuit damage. Ensure replacement parts meet the same AEC-Q100 automotive qualification if applicable.
