MAX6468XS16D3-T

Overview

The MAX6468XS16D3-T is a microprocessor supervisory reset circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors single power-supply voltages ranging from +1.8V to +5.0V and asserts an active-low, push-pull reset signal if the supply drops below its preset threshold of 1.575V. The device features an edge-triggered, one-shot manual reset function and operates within a temperature range of -40°C to +125°C. It is housed in a compact SC-70-4 surface-mount package.

Feature Summary

• Edge-triggered, one-shot manual reset function ensures the microprocessor enters reset mode for a fixed timeout period only, even during continuously asserted manual resets.
• Factory-trimmed threshold voltage options accommodate various supply voltages and tolerances without requiring external components.
• Active-low, push-pull output provides robust drive capability for reliable system reset signaling.

Applications

• Microprocessor (µP) supervisory circuits
• Single power-supply voltage monitoring systems
• Embedded systems requiring manual reset functionality

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as '+T' or '-T' may indicate specific packaging or compliance differences. Confirm availability status with authorized distributors, as this component may be subject to limited supply or end-of-life restrictions. Ensure the selected variant matches the required threshold voltage and package type for your design.

Selection Notes

Select this component when a low-power, single-channel supervisor with manual reset capability is required. Verify that the 1.575V threshold aligns with the monitored rail's minimum operating voltage. Consider the SC-70-4 package constraints for PCB layout. Check for alternative threshold variants within the MAX6468 family if the 1.575V setting does not match the application requirements.

Part Context

The MAX6468 series belongs to Maxim Integrated's line of microprocessor supervisory circuits designed to enhance system reliability. These devices replace traditional manual reset circuits by providing precise voltage monitoring and controlled reset timing. The series offers various factory-set thresholds and timeout periods to suit different microprocessor platforms.

Replacement Considerations

Consult the official MAX6468 datasheet for direct pin-compatible alternatives with different threshold voltages or timeout periods. Verify that any substitute part maintains the same SC-70-4 package and electrical characteristics to ensure seamless integration.
