MAX6368HKA46+T

Overview

The MAX6368HKA46+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features an adjustable overvoltage threshold. The device provides a reset output with a fixed delay time of 280ms. It includes a battery backup switch for seamless power transition and utilizes a Chip Enable signal for power management. The component is housed in an SOT-23-8 package and supports surface mount installation.

Feature Summary

• Integrates a battery backup switch to maintain system integrity during power transitions
• Features an adjustable overvoltage detection threshold for flexible monitoring configurations
• Includes a Chip Enable input to minimize quiescent current consumption
• Provides a dedicated reset output with a guaranteed 280ms delay period

Applications

• Microprocessor system supervision
• Battery-powered portable equipment
• Consumer electronics power management
• Industrial control systems requiring voltage monitoring

Procurement Notes

Verify the specific suffix 'KA46' against official Analog Devices documentation to confirm the exact adjustable threshold configuration, as suffixes define functional parameters. Confirm availability status through authorized distributors, as this part may be subject to limited supply or end-of-life restrictions. Ensure the SOT-23-8 footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when a low quiescent current supervisory circuit with adjustable overvoltage protection is required. The inclusion of a battery backup switch makes it suitable for applications where data retention during power loss is critical. Consider the 280ms reset delay and the need for a Chip Enable pin when designing the power sequence. Verify that the operating temperature range of -40C to +85C meets the environmental constraints of the application.

Part Context

The MAX6368 series comprises low-power microprocessor supervisory circuits designed for reliable system monitoring. This specific variant belongs to the H-series, which typically denotes specific output characteristics and enable features within the family. The device is part of Analog Devices' portfolio aimed at providing robust power management solutions for embedded systems requiring precise voltage tracking.

Replacement Considerations

Consult the official Analog Devices MAX6368 datasheet for cross-reference information. Potential substitutes must match the SOT-23-8 package, 1V-5.5V operating range, and include both battery backup and chip enable functionalities. Verify that any alternative device offers comparable reset delay times and adjustable overvoltage thresholds to ensure circuit compatibility.
