MAX6301CSA+TCL0

Supervisors Overview

The MAX6301CSA+TCL0 is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5V and features an adjustable reset threshold starting from 1.24V. The device includes a watchdog timer with a timeout period adjustable via external capacitors, offering a 500x multiplier option. It provides a 4ms reset delay and draws only 7µA of supply current. The output is active-low open-drain. It is housed in an SOIC-8 surface-mount package and functions reliably between 0°C and +70°C with 2% accuracy.

Supervisors Feature Summary

• Provides adjustable reset threshold and timeout periods using external passive components
• Integrates a watchdog timer with selectable 500x timeout extension capability
• Features immunity to power-supply transients to prevent false resets
• Delivers active-low open-drain reset output for direct interface with logic systems

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 TCL0 against official datasheets to confirm tape-and-reel packaging and temperature grade variations. Ensure compatibility with existing PCB footprints for the SOIC-8 package. Confirm that the adjustable threshold requirements align with the system's voltage rails. Validate that the open-drain output configuration meets the downstream logic input specifications.

Supervisors Selection Notes

Select this component when precise control over reset timing and threshold voltages is required beyond fixed-voltage supervisors. The adjustable watchdog feature makes it suitable for complex firmware environments where standard timeouts are insufficient. Consider the low quiescent current for battery-operated designs. Ensure external resistor and capacitor values can be accurately implemented to meet specific timing and voltage constraints.

Supervisors Part Context

This part belongs to the MAX6301 series of low-power µP supervisory circuits. The series offers maximum adjustability for reset and watchdog functions. Variants differ primarily in reset output structure and package type. The MAX6301 specifically provides an active-low open-drain output. It is designed for applications demanding high reliability and customizable power management parameters.

Supervisors Replacement Considerations

Direct substitutes include other MAX6301 variants such as MAX6301CSA or MAX6301CPA, differing mainly in package style (SOIC vs. PDIP) or output polarity. Cross-reference with MAX6302/MAX6303/MAX6304 if different output configurations like push-pull are needed. Verify pinout compatibility before substitution.
