MAX6740XKVRD3

Supervisors Overview

The MAX6740XKVRD3+T is a low-power dual- or triple-voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5 V and supports threshold voltages from 900 mV to 3.3 V. The device features an active-low, open-drain output type and includes a manual reset function without a watchdog timer. It has a reset delay time of 225 ms and a maximum power supply voltage of 5.5 V. Operating temperatures range from -40°C to +85°C with a quiescent current of 5 µA or 10 µA. The component is housed in an SC-70-5 package.

Supervisors Feature Summary

• Supports dual- or triple-voltage monitoring configurations for comprehensive system supervision.
• Includes a manual reset input for controlled system recovery operations.
• Features low quiescent current consumption suitable for battery-powered applications.
• Provides an active-low open-drain output for flexible interface compatibility.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing voltage supervision
• Embedded controllers requiring manual reset capabilities

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6740 family. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or discontinuation. Ensure the selected variant matches the required threshold voltages and package type for your design.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with minimal power impact. The manual reset feature distinguishes it from variants lacking this control. Verify that the open-drain output aligns with the downstream logic requirements. Consider the operating temperature range and supply voltage limits to ensure compatibility with the target application environment.

Supervisors Part Context

This component belongs to the MAX6740 series of low-power supervisory circuits designed for portable electronics. It offers configurable voltage monitoring options in a compact surface-mount package. The series is engineered to provide reliable system protection while maintaining low energy consumption, making it suitable for space-constrained and battery-sensitive designs.

Supervisors Replacement Considerations

Check for MAX6740XKVDD3+T if an open-drain output with manual reset is still required but different thresholds are needed. Verify MAX6740XKRVD3+T if push-pull output is acceptable instead of open-drain. Consult the manufacturer's cross-reference guide for updated availability and pin-compatible alternatives.
