MAX6301CUA+T

Supervisors Overview

The MAX6301CUA+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.24 V to 5.5 V and features an adjustable reset threshold with 2% accuracy. The device provides a single active-low, open-drain output with a fixed 4 ms reset delay time. It integrates a watchdog timer function and consumes only 7 µA of operating current. Designed for commercial temperatures between 0°C and +70°C, it is housed in an 8-pin uMAX or uSOP surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Features adjustable reset threshold voltage for flexible monitoring
• Provides active-low open-drain reset output signal
• Operates with ultra-low power consumption suitable for battery applications

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-powered embedded systems needing voltage supervision
• Industrial control units utilizing watchdog functionality
• Communication equipment requiring reliable power sequencing

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to +70°C. Ensure the lead-free '+ designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the exact pinout for the uMAX/uSOP package variant to prevent footprint mismatches during PCB design integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog timing is required. It is appropriate for designs where the reset threshold must be adjusted via external resistors rather than using fixed internal values. Consider this part for space-constrained applications due to its small 8-lead package. Verify that the 4 ms delay meets the startup timing requirements of the monitored processor or logic circuit.

Supervisors Part Context

This part belongs to the MAX6301 family of low-power supervisory circuits from Maxim Integrated. The family includes variants with different packages, such as the MAX6301CSA+ in SOIC-8 and the MAX6301ESA+T in SOP-8. These devices share core functionalities including adjustable thresholds and watchdog timers, differing primarily in physical footprint and manufacturing lot specifications.

Supervisors Replacement Considerations

Direct substitutes include other MAX6301 variants like MAX6301CSA+ or MAX6301ESA+T, provided the package type matches the existing board layout. Ensure any replacement maintains the same 7 µA current draw and 4 ms delay characteristics to preserve system stability.
