MAX6301EPA

Supervisors Overview

The MAX6301EPA is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5V and features an adjustable reset threshold starting from 1.24V using external resistors. The device includes an adjustable watchdog timer with a selectable 500x multiplier option. Key electrical parameters include a typical supply current of 7µA, a reset delay time of 4ms, and accuracy of 2%. It provides an active-low, open-drain output and is housed in an 8-pin PDIP package.

Supervisors Feature Summary

• Adjustable reset threshold and timeout periods via external components
• Integrated watchdog timer with 500x timeout extension capability
• Low power consumption suitable for battery-operated systems
• Immunity to power-supply transients during reset assertion

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix 'EPA' against official Analog Devices documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing PCB footprints for the 8-pin PDIP configuration. Cross-reference the adjustable resistor network requirements with the datasheet to validate design constraints before procurement.

Supervisors Selection Notes

Select this component when adjustable reset thresholds are required above 1.24V. Consider the 7µA quiescent current for low-power applications. Verify that the open-drain output interface matches the system logic levels. Evaluate the need for the watchdog function and available pins for external capacitor connections to set timeout values.

Supervisors Part Context

The MAX6301 series belongs to Maxim's family of low-power µP supervisory circuits. It offers flexibility through adjustable parameters compared to fixed-threshold counterparts. The device integrates reset generation and watchdog functionality in a single compact package, simplifying design for critical system monitoring applications.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6301 series such as MAX6301CPA or MAX6301CSA. Verify that substitute parts maintain the same adjustable threshold capabilities and output structure. Confirm package compatibility if transitioning between PDIP and SO variants.
