MAX6744XKWTD3+T

Supervisors Overview

The MAX6744XKWTD3+T is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features dual voltage monitoring channels housed in an SC-70-5 package. The device supports manual reset input and includes a watchdog timer function. Key electrical parameters include a maximum supply voltage of 5.5 V, a typical operating current of 5 uA, and a reset delay time of 7.59 ms. It operates within a temperature range of -40°C to +125°C with 2% accuracy.

Supervisors Feature Summary

• Dual-channel voltage supervision for independent monitoring
• Capacitor-adjustable timeout delay for flexible timing control
• Integrated watchdog timer with manual reset capability
• Low quiescent current consumption for power efficiency

Supervisors Applications

• Embedded microprocessor systems requiring voltage supervision
• Portable electronic devices needing low-power monitoring
• Industrial control systems with harsh environmental requirements

Supervisors Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the specific threshold voltage variant matches the design requirement, as the MAX6744 series offers multiple options. Ensure the SC-70-5 footprint aligns with the PCB layout. Check RoHS compliance status if required by regional regulations. Validate the operating temperature range against the application environment.

Supervisors Selection Notes

Select this component when dual voltage rails require simultaneous supervision in a minimal footprint. Consider the capacitor-adjustable timeout feature if precise reset timing is critical. Evaluate the low standby current for battery-operated applications. Compare threshold voltages across the MAX6744 family to match specific rail levels. Verify the open-drain output compatibility with the downstream logic interface.

Supervisors Part Context

This part belongs to the MAX6744 family of low-power microprocessor supervisory circuits. The family provides dual or triple voltage monitoring solutions in compact packages. These devices are designed for embedded systems where space and power consumption are constrained. The MAX6744 series integrates watchdog and reset functions to enhance system reliability.

Supervisors Replacement Considerations

Check for other MAX6744 variants with different threshold voltages or package types. Verify pin-to-pin compatibility with existing designs before substitution. Ensure the replacement part supports the required operating temperature range.
