MAX6342LUT+T

Overview

The MAX6342LUT+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 4.63V with an accuracy of 1.5%. The device provides power-fail detection and includes a reset delay time of 180 ms. It draws a typical operating supply current of 30 uA and dissipates up to 320 mW. The component is housed in a SOT-23-6 surface-mount package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates power-fail comparator for monitoring input voltage levels
• Provides active high and active low push-pull output configurations
• Operates with low quiescent current consumption suitable for battery applications

Applications

• Microprocessor system reset generation
• Battery backup switching circuits
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'LUT' against the official datasheet to confirm the exact threshold voltage and package variant, as minor suffix changes can alter electrical characteristics. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the sourcing channel is authorized to guarantee authenticity, as this component may have limited availability or be subject to restricted distribution channels depending on the region.

Selection Notes

Select this component when a fixed 4.63V threshold is required for systems powered between 1V and 5.5V. The SOT-23-6 package is ideal for space-constrained designs. Consider the 180ms reset delay and 1.5% accuracy for timing-sensitive applications. Verify that the single-input architecture meets the monitoring requirements without needing additional external comparators.

Part Context

This part belongs to the MAX634x series of microprocessor supervisors from Analog Devices/Maxim Integrated. These devices are designed to provide reliable reset signals and power-fail indications for digital systems. The series typically offers various threshold voltages and package options to accommodate different design constraints while maintaining low power consumption and high accuracy standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX634x family that offer similar threshold voltages. Verify if newer generations from Analog Devices provide equivalent functionality with updated packaging or enhanced specifications.
