MAX6363LUT29+T

Overview

The MAX6363LUT29+T 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 1.5 V to 5.5 V and features a fixed reset threshold voltage of 2.93 V. The device provides an active-low, push-pull output with a reset delay time of 280 ms. It includes a battery backup switch for seamless power transition monitoring. The component draws a typical operating supply current of 15 µA and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-6 surface-mount format, it lacks manual reset and watchdog timer capabilities.

Feature Summary

• Integrates a battery backup switch to monitor transitions between main and auxiliary power sources
• Provides a dedicated reset output signal triggered by undervoltage conditions below the set threshold
• Features a fixed internal reset delay to ensure stable power-up sequencing for connected logic

Applications

• Microprocessor system power supervision
• Battery backup power source monitoring
• Embedded controller voltage tracking

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity and pin alignment against SOT-23-6 specifications during receipt inspection. Validate datasheet parameters against specific lot documentation to ensure compliance with electrical thresholds and thermal ratings prior to integration into final assemblies.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage monitoring without manual reset or watchdog functionality. The push-pull output configuration suits applications needing direct drive capability. Ensure the 15 µA quiescent current aligns with low-power design constraints and that the SOT-23-6 footprint matches the PCB layout requirements.

Part Context

This part belongs to the MAX6363L series of low-power microprocessor supervisors. It shares family characteristics such as low supply current and battery backup switching but differs from other variants in its specific threshold voltage, output type, and package configuration. The 'L' suffix typically denotes specific threshold options within the broader MAX6363 product line.

FAQ
