MAX6344RUT-T

Overview

The MAX6344RUT-T is a microprocessor supervisory circuit in a 6-pin SOT-23 package. It monitors a single voltage input with a threshold of 4.38V and an accuracy of 1.5%. The device features an active-high, push-pull output and a reset delay time of 100ms minimum. It operates within a supply voltage range of +1V to +5.5V and supports temperatures from -40°C to +125°C.

Feature Summary

• Provides factory-trimmed reset threshold voltages for system reliability
• Features active-high push-pull output for direct logic interfacing
• Includes power-fail comparator for low-battery detection or monitoring

Applications

• Digital system power supply monitoring
• Microprocessor reset control
• Low-battery detection circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm RoHS compliance status as some variants may differ. Check current availability as this component may be subject to limited supply or end-of-life restrictions depending on the manufacturer's production schedule.

Selection Notes

Select this part when an active-high output is required, distinguishing it from the MAX6343 which offers active-low outputs. Ensure the 4.38V threshold aligns with the monitored rail. Consider the SOT-23-6 package size constraints and the wide operating temperature range suitable for industrial environments.

Part Context

Part of the MAX6342–MAX6345 family of µP supervisory circuits designed to improve system reliability compared to discrete components. These devices offer factory-trimmed thresholds from 2.33V to 4.63V and operate with supply voltages between +1V and +5.5V.

Replacement Considerations

The MAX6345LUT+T is a similar 6-pin supervisor but features a different threshold (4.63V) and reset delay (180ms). Verify electrical compatibility before substitution.
