MAX6741XKWTD3+

Supervisors Overview

The MAX6741XKWTD3+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.3V to 5.5V and features an adjustable reset threshold voltage of 2.313V. The device provides manual reset functionality and includes a watchdog timer with a capacitor-adjustable timeout delay. It utilizes an open-drain active-low output and is housed in a compact SOT-23-8 package. The component supports operation across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Supervisors Feature Summary

• Integrates a watchdog timer with externally adjustable timeout delay via an external capacitor
• Features a manual reset input for system control flexibility
• Provides an active-low open-drain reset output signal
• Supports extended industrial operating temperatures up to +125°C

Supervisors Applications

• Embedded systems requiring power supply supervision
• Microcontroller-based designs needing watchdog protection
• Industrial equipment operating in harsh thermal environments
• Portable devices utilizing low-voltage power sources

Supervisors Procurement Notes

Verify the specific suffix KWTD3 against official datasheets to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with your PCB footprint for the SOT-23-8 package. Confirm that the adjustable threshold and watchdog timing components align with your system's timing constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a combination of power monitoring and programmable watchdog functionality is required in a small form factor. The adjustable threshold allows customization for various rail voltages. Consider the SOT-23-8 package size constraints and the need for external capacitors for the watchdog timer when evaluating alternative supervisory ICs.

Supervisors Part Context

This part belongs to the MAX6741 series of supervisory circuits designed for low-power applications. The series offers configurable reset thresholds and watchdog timers to protect microprocessors and memory systems. The MAX6741 variant specifically integrates these functions into a single chip, reducing component count and board space compared to discrete solutions.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the same package type, voltage range, and functional capabilities such as the adjustable watchdog timer.
