MAX6363LUT31+

Overview

The MAX6363LUT31+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.0V to 5.5V and features a fixed reset threshold voltage of 3.08V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It includes a battery backup switch for seamless power transition monitoring. The component is housed in a compact SOT-23-6 package and supports manual reset functionality via an external input.

Feature Summary

• Integrates a battery backup switch to monitor transitions between main power and backup sources
• Provides manual reset capability through an external input pin for system control
• Delivers a deterministic reset pulse with a standard delay time after power-up or fault detection

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery backup switching circuits for data retention
• Manual reset inputs for industrial control panels

Procurement Notes

Verify the specific suffix 'LUT31' against official datasheets to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and check current availability as distribution may be limited. Ensure the ordering information matches the required electrical characteristics for the target application design.

Selection Notes

Select this component when a fixed 3.08V threshold is required for single-supply monitoring. Consider the SOT-23-6 package size constraints and the need for manual reset functionality. Evaluate the low quiescent current requirements against the system's power budget and operating temperature range specifications.

Part Context

This part belongs to the MAX6363 series of low-power microprocessor supervisors. The series is designed for applications requiring reliable power management in portable and battery-operated devices. It complements other Maxim Integrated PMIC solutions by providing essential voltage supervision and reset generation capabilities.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative part maintains the same SOT-23-6 footprint, 3.08V threshold, and manual reset feature compatibility.
