MAX6342RUT+

Overview

The MAX6342RUT+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +1V to +5.5V and features a factory-trimmed reset threshold voltage of 2.33V. The device provides an active-low push-pull reset output and includes a manual reset (MR) input for system control. It is housed in a compact SOT-23-6 surface-mount package, designed for low-power digital systems requiring reliable power monitoring.

Feature Summary

• Provides active-low push-pull reset output for stable system initialization
• Includes manual reset input for direct user control over reset state
• Features a dedicated +1.25V threshold detector for power-fail warnings or battery monitoring

Applications

• Digital system power supply monitoring
• Low-battery detection circuits
• Power-fail warning generation

Procurement Notes

Verify the specific suffix RUT+ against the official datasheet to confirm the SOT-23-6 package and lead-free status. Confirm availability as distribution channels may list limited stock or end-of-life status. Ensure the 2.33V threshold matches the design requirement before procurement.

Selection Notes

Select this component when a fixed 2.33V reset threshold is required for voltages between 1V and 5.5V. The inclusion of a manual reset input distinguishes it from variants like the MAX6343/44. Consider the SOT-23-6 footprint for space-constrained PCB layouts.

Part Context

Part of the MAX6342–MAX6345 family of µP supervisory circuits. This series improves system reliability compared to discrete components. The MAX6342 variant is unique within the family for its manual reset capability and push-pull output configuration.

Replacement Considerations

Check MAX6343RUT+ and MAX6344RUT+ for identical electrical performance without manual reset. Verify pin compatibility if substituting with other Maxim supervisor ICs.
