MAX6318LHUK49BX+T

Supervisors Overview

The MAX6318LHUK49BX+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in a 5-pin SOT-23 package. It features a watchdog timer and manual reset capability with a push-pull output. The device operates with an operating supply current of 10 uA and has a power dissipation rating of 571 mW. It monitors a single voltage channel with an overvoltage threshold of 4.974 V and does not include power fail detection.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Includes manual reset input functionality
• Provides push-pull output drive

Supervisors Applications

• Microprocessor reset circuits
• Watchdog timer applications
• Manual reset systems

Supervisors Procurement Notes

Verify the specific suffix 'BX+T' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the component is sourced from authorized distributors to guarantee authenticity. Check for RoHS compliance status as indicated by the '+' suffix. Confirm availability as some variants may be obsolete.

Supervisors Selection Notes

Select this component when a low standby current of 10 uA is required for battery-operated or power-sensitive designs. The fixed 4.9V threshold suits systems requiring precise voltage supervision without external resistors. The integrated watchdog simplifies design by reducing external component count compared to discrete solutions.

Supervisors Part Context

This part belongs to the MAX6318 series of supervisory circuits. It is designed to monitor voltage levels and provide reset signals to microprocessors. The series typically offers various threshold voltages and packaging options to suit different application requirements within embedded systems.

Supervisors Replacement Considerations

The MAX6318LHUK49BX-T is listed as obsolete. Verify if MAX6318MHUK46BZ-T serves as a functional substitute, noting the difference in threshold voltage (4.6V vs 4.9V). Cross-reference pinouts and electrical specifications before substitution.
