MAX6342MUT+T

Overview

The MAX6342MUT+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 factory-trimmed reset threshold voltage of 4.38V. The device provides an active-low push-pull reset output and includes a manual reset (MR) input for system control. Designed for digital systems, it monitors power supplies to enhance reliability. It is housed in a compact SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides active-low push-pull reset output for reliable system initialization
• Includes manual reset input for direct user control over system state
• Features factory-trimmed voltage threshold for accurate monitoring without external components

Applications

• Digital system power supply monitoring
• Microprocessor supervisory circuits
• Low-voltage detection applications

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate part markings against official datasheet specifications to prevent counterfeit infiltration during acquisition.

Selection Notes

Select this component when a fixed 4.38V threshold with push-pull output is required. Consider the SOT-23-6 package for space-constrained designs. Evaluate the manual reset feature necessity against simpler open-drain alternatives. Verify that the +1V to +5.5V input range matches the target system voltage rails.

Part Context

This part belongs to the MAX6342–MAX6345 family of µP supervisory circuits. These devices replace discrete components to improve system accuracy. The family offers various threshold voltages and output configurations. The MAX6342 specifically distinguishes itself with its push-pull output and manual reset capability compared to other variants in the series.

Replacement Considerations

Check for MAX6342MUT without the suffix if lead-free compliance is not mandatory. Verify pin compatibility with MAX6343 or MAX6344 if output type differences are acceptable.
