MAX6301CUA

Supervisors Overview

The MAX6301CUA+ is a low-power microprocessor supervisory circuit designed for adjustable reset and watchdog timer functions. It operates within a supply voltage range of 2.4V to 5.5V, with a threshold voltage starting at 1.24V. The device features an active-low open-drain output and a 4ms reset delay time. It consumes only 7µA of operating current and offers a 2% accuracy rating. The component is housed in an SOIC-8 surface-mount package and supports an adjustable overvoltage threshold.

Supervisors Feature Summary

• Provides adjustable reset thresholds and timeout periods using external passive components
• Includes a watchdog timer function with selectable 500x timeout multiplier
• Features immunity to power-supply transients to prevent false resets

Supervisors Applications

• Critical microprocessor monitoring in embedded systems
• Portable battery-powered computers and devices
• Medical equipment requiring reliable power supervision
• Intelligent instruments and set-top boxes

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required output structure and package type for your design. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and environmental certifications before finalizing procurement.

Supervisors Selection Notes

Select this component when adjustable reset thresholds are required rather than fixed-voltage options. Consider the 7µA quiescent current for battery-operated applications. Verify that the open-drain output configuration aligns with the system logic levels. Evaluate the need for the watchdog multiplier feature if extended timeout periods are necessary for complex software sequences.

Supervisors Part Context

This part belongs to the MAX6301 series of low-power µP supervisory circuits from Analog Devices/Maxim Integrated. The series provides maximum adjustability for reset and watchdog functions through external resistors and capacitors. Variants within the family differ primarily in reset output structures and package types, offering flexibility for various space-constrained designs.

Supervisors Replacement Considerations

Consult the official selector guide for direct functional equivalents such as the MAX6302, MAX6303, or MAX6304. These variants share similar core features but may differ in reset output polarity or drive capability. Verify package compatibility and electrical specifications before substitution.
