MAX6301CUA+

Supervisors Overview

The MAX6301CUA+ is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.0V to 5.5V and features an adjustable overvoltage threshold with 2% accuracy. The device provides a reset output with a fixed delay of 4ms and includes an integrated watchdog timer. It is available in an 8-pin uMAX package and supports operation temperatures from 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault monitoring
• Features adjustable overvoltage detection thresholds
• Provides active-low open-drain reset output

Supervisors Applications

• Portable battery-powered equipment
• Consumer electronics
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix 'CUA+' against official datasheets to confirm the commercial temperature grade and uMAX package variant. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure compatibility with existing PCB footprints for 8-lead micro-packages before procurement.

Supervisors Selection Notes

Select this component when adjustable overvoltage protection is required alongside standard power-on reset functionality. The low quiescent current makes it suitable for energy-constrained designs. Verify that the 4ms reset timeout meets the target system's initialization timing requirements.

Supervisors Part Context

This part belongs to the MAX6301 series of supervisory circuits designed for monitoring single voltage rails. It complements other Maxim Integrated PMIC solutions by providing essential reset generation and watchdog capabilities in a compact surface-mount package.

Supervisors Replacement Considerations

Direct substitutes include the MAX6301CSA+ for SOIC-8 packaging variants. Cross-reference pinouts and electrical specifications carefully when considering alternative packages within the same family.
