MAX6363HUT46+T

Overview

The MAX6363HUT46+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 up to 5.5 V and features a fixed threshold voltage of 4.63 V for monitoring power rails. The device provides an active low, push-pull output and includes a battery backup switch capability. It incorporates a manual reset input and lacks a watchdog timer. The reset delay time is specified at 180 ms. Operating temperatures range from -40 C to +125 C, with a typical quiescent current of 27 uA.

Feature Summary

• Integrates a manual reset input for direct system control
• Features a battery backup switch for seamless power transition management
• Provides an active low, push-pull output driver

Applications

• Microprocessor power supply monitoring in industrial systems
• Battery-powered embedded devices requiring backup switching
• Portable electronics needing low-quiescent current supervision

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status via official datasheets before integration. Check current lifecycle status as availability may vary. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input voltage monitoring. Consider the manual reset feature if external reset control is necessary. Evaluate the push-pull output drive strength against load requirements. Compare operating temperature ranges and quiescent current consumption against other series variants like MAX6363PUT46+T for optimal power efficiency.

Part Context

This part belongs to the MAX6363P series of low-power MPU supervisors. It shares functional similarities with other members but differs in specific thresholds and package types. The H suffix typically denotes specific threshold voltages within the family. It complements broader supervisory solutions offering integrated reset generation and battery management functions.

Replacement Considerations

MAX6363PUT46+T offers similar functionality with open-drain output instead of push-pull. MAX6363LUT46+T provides comparable features with different output characteristics. Verify pin compatibility and electrical parameters before substitution.
