MAX6324BUT46+T

Supervisors Overview

The MAX6324BUT46+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single power supply input with a fixed threshold voltage of 4.63 V and an overvoltage threshold of 4.75 V. The device features an active low, open-drain reset output and includes both a windowed watchdog timer and a manual reset input. It operates within a supply voltage range up to 5.5 V, consumes 27 uA of quiescent current, and maintains accuracy within 1.5%. The component supports a reset delay time of 180 ms and functions reliably across an extended temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Integrates a windowed watchdog timer for monitoring processor activity outside expected operational windows
• Includes a manual reset input allowing external assertion of the reset signal
• Provides an active low, open-drain reset output compatible with various logic families
• Operates with low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system supervision in digital electronics
• Battery-powered devices requiring extended temperature operation
• Industrial control systems needing watchdog functionality
• Consumer electronics with strict power management requirements

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the package type matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for any specific ordering increments or factory-direct availability constraints before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required alongside integrated watchdog and manual reset capabilities. Consider the SOT-23-6 package size for space-constrained designs. Evaluate the 1.5% accuracy specification against system tolerance needs. Compare the 27 uA current draw against other supervisory circuits if ultra-low power is critical.

Supervisors Part Context

This part belongs to the MAX6324 series of microprocessor supervisory circuits. The series offers various threshold voltages and package options. The MAX6324 variant specifically provides an open-drain output. Other family members may include push-pull outputs or different timeout periods. The series is designed for reliable power monitoring in demanding environments.

Supervisors FAQ

What is the function of the windowed watchdog timer in the MAX6324BUT46+T?

The windowed watchdog timer monitors processor activity to ensure it remains within an expected operational window, asserting reset if activity falls outside these bounds.

Can the reset output be manually triggered on the MAX6324BUT46+T?

Yes, the device includes a manual reset input that allows external assertion of the reset signal independently of the power supply voltage.
