MAX6343RUT+T

Overview

The MAX6343RUT+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in a SOT-23-6 surface-mount package. It monitors a single input voltage with a fixed threshold of 2.63V. The device features an active-low open-drain reset output and includes a power-fail comparator. It operates within a supply voltage range of 1.2V to 5.5V and supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a power-fail comparator for system monitoring
• Provides active-low open-drain reset signal output
• Operates across wide industrial temperature ranges

Applications

• Microprocessor reset circuits
• Portable equipment power management
• Battery-powered systems supervision

Procurement Notes

Verify the specific suffix 'RUT' against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current manufacturer declarations. Ensure the source document matches the exact part number to avoid confusion with similar MAX6343 variants that may have different thresholds or packages.

Selection Notes

Select this component when a fixed 2.63V threshold is required for MPU supervision. The SOT-23-6 package suits space-constrained designs. Verify compatibility with the target system's logic levels due to the open-drain output configuration. Consider the operating temperature range if deployed in harsh environments.

Part Context

This part belongs to the MAX6343 series of supervisory circuits designed for low-voltage applications. It serves as a critical component for ensuring reliable system startup and recovery in embedded electronics. The series typically offers various threshold options and package configurations to meet diverse design requirements.

Replacement Considerations

Check for MAX6343 variants with identical 2.63V thresholds and SOT-23-6 packaging. Verify functional equivalence regarding the power-fail comparator and reset pulse width before substitution.
