MAX6301CUA+CLH

Supervisors Overview

The MAX6301CUA+CLH is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.3V to 5.5V and features an adjustable reset threshold starting from 1.24V. The device includes an adjustable watchdog timer with a selectable 500x multiplier option, allowing for flexible timeout periods determined by external capacitors. It provides a push-pull or open-drain reset output and maintains a typical supply current of 4µA. The component is housed in an 8-pin µMAX package and is designed for critical monitoring applications.

Supervisors Feature Summary

• Adjustable reset threshold and timeout periods via external resistors and capacitors
• Watchdog timer with selectable 500x timeout multiplier
• Low power consumption with 4µA supply current
• Immunity to power-supply transients

Supervisors Applications

• Medical equipment
• Embedded controllers
• Intelligent instruments
• Portable battery-powered computers

Supervisors Procurement Notes

Verify the specific suffix CLH against official datasheets to confirm pinout and electrical characteristics, as suffixes may indicate tape-and-reel packaging or specific temperature grades. Ensure compatibility with existing PCB footprints for the 8-pin µMAX package. Confirm RoHS compliance status through manufacturer documentation prior to integration into production designs.

Supervisors Selection Notes

Select this component when design requirements demand high adjustability for reset thresholds and watchdog timeouts using passive components. It is suitable for space-constrained applications due to the compact µMAX package. Consider the 4µA quiescent current for battery-operated systems. Verify that the required reset output type (push-pull vs. open-drain) matches the system logic interface.

Supervisors Part Context

The MAX6301 belongs to the Maxim Integrated family of low-power µP supervisory circuits. This series offers maximum adjustability for reset and watchdog functions, differing primarily in reset output structure among variants like the MAX6301–MAX6304. The MAX6301 specifically provides a RESET output option, distinguishing it from other members of the family that may offer complementary outputs.

Supervisors Replacement Considerations

Direct replacements include MAX6301CSA+ and MAX6301CPA+. These parts share identical functional specifications and pinouts but differ in package style (SOIC or PDIP). Verify that the alternative package fits the available board space and soldering capabilities.
