MAX6824SUK+

Supervisors Overview

The MAX6824SUK+ is a single-input voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 2.93 V. The device provides an active-low, push-pull output with a manual reset input capability. It includes a watchdog timer function and maintains a typical quiescent current of 5 uA. The component supports a reset delay time of 200 ms and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates voltage monitoring, watchdog timer, and manual reset functionality in a compact package
• Provides factory-trimmed reset threshold voltages for precise supervision without external components
• Features ultra-low power consumption suitable for battery-operated applications
• Ensures reliable system recovery through guaranteed reset output validity down to low supply voltages

Supervisors Applications

• Microprocessor (µP) supervisory circuits requiring manual reset inputs
• Battery-powered portable devices needing low standby current
• Systems requiring watchdog timer protection against software failures
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'S' indicates the 2.93 V threshold variant when sourcing replacements. Confirm RoHS compliance status via official manufacturer documentation before integration. Check current availability as distribution channels may list limited stock or end-of-life statuses. Ensure the SOT-23-5 footprint matches your PCB design requirements precisely.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-supervision tasks. Consider the manual reset feature if user intervention capabilities are necessary. Evaluate the 5 uA quiescent current against total system power budgets. Verify that the active-low push-pull output drives the target logic levels correctly.

Supervisors Part Context

This part belongs to the MAX68xx series of nanopower microprocessor supervisory circuits. These devices combine voltage monitoring with watchdog timers and manual resets. The series is designed for applications demanding high reliability and low power consumption in small form factors like the SOT-23-5 package.

Supervisors Replacement Considerations

Direct substitutes include other MAX68xx variants with compatible thresholds and packages. Verify pinout compatibility and electrical specifications such as reset timeout and quiescent current before substitution.
