MAX6824LUK+

Supervisors Overview

The MAX6824LUK+T is a single-channel, low-power voltage 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 a fixed threshold voltage with options including 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V. The device incorporates a watchdog timer and provides a reset delay time of 320 ms. It supports active high, active low, and push-pull output configurations. Operating temperatures span from -40°C to +125°C, with a typical quiescent current of 10 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides configurable reset output polarities including active high and active low
• Ensures valid reset output down to 1 V supply voltage
• Offers power supply glitch immunity

Supervisors Applications

• Portable equipment requiring low power consumption
• Battery-operated systems needing voltage supervision
• Microprocessor reset circuits in embedded applications

Supervisors Procurement Notes

Verify the specific suffix (e.g., LUK) against the official datasheet to confirm the exact threshold voltage option, as the MAX6824 series offers multiple fixed voltage variants. Confirm package type SOT-23-5 and RoHS compliance status directly with the manufacturer or authorized distributors before procurement.

Supervisors Selection Notes

Select this component when a single-supervisor circuit with integrated watchdog functionality is required. Ensure the chosen threshold voltage matches the monitored rail. Consider the 320 ms reset timeout and operating temperature range (-40°C to +125°C) for environmental compatibility. Verify output drive requirements against the available push-pull or open-drain options.

Supervisors Part Context

The MAX6824 belongs to the Maxim Integrated family of low-voltage supervisory circuits designed for portable and battery-powered applications. It shares functional similarities with the ADM6824 series but is optimized for specific voltage thresholds and packaging constraints within the SOT-23-5 form factor.

Supervisors Replacement Considerations

The ADM6824ZYRJZ-RL7 is a comparable alternative offering similar supervisory functions in an SOT-23 package. Verify pinout compatibility and threshold voltage alignment before substitution.
