MAX6467XS22D3+T

Overview

The MAX6467XS22D3+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 a reset signal if the supply voltage drops below its preset threshold of 2.2V. The device features an edge-triggered, one-shot manual reset function that ensures the microprocessor enters reset mode for a fixed timeout period only, even during continuously asserted manual resets. It operates within a temperature range of -40°C to +125°C, consumes 7µA of quiescent current, and supports a maximum supply voltage of 5.5V with a reset delay time of 225ms.

Feature Summary

• Edge-triggered, one-shot manual reset function prevents indefinite reset states
• Monitors single power-supply voltages from +1.8V to +5.0V
• Active low, open-drain output type
• Factory-trimmed threshold voltage for accuracy

Applications

• Microprocessor (µP) supervisory circuits
• Voltage monitoring in portable electronics
• Battery-powered systems requiring low quiescent current
• Industrial control systems operating in extreme temperatures

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices/Maxim Integrated before procurement planning. Ensure packaging specifications match design requirements.

Selection Notes

Select this component when a fixed threshold voltage near 2.2V is required for single-supply monitoring. Consider the SC-70-4 package size for space-constrained designs. Evaluate the 7µA quiescent current against system power budgets. Verify compatibility with the target microprocessor's reset input requirements.

Part Context

Part of the MAX6467/MAX6468 series of microprocessor supervisory circuits. Designed to improve system reliability compared to traditional manual reset supervisory circuits by providing a controlled reset duration. Manufactured using BICMOS technology.

Replacement Considerations

Consult official Analog Devices/Maxim Integrated documentation for verified substitute part numbers. Cross-reference threshold voltage, package type, and electrical characteristics carefully.
