MAX6468XS22D3+T

Overview

The MAX6468XS22D3+T is a microprocessor supervisory reset circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 typical reset delay 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
• Asserts reset when supply voltage drops below preset threshold
• Operates across extended industrial temperature ranges

Applications

• Microprocessor (µP) supervisory circuits
• Single power-supply monitoring systems
• Embedded systems requiring reliable reset management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status (+ suffix indicates lead-free). Check current lifecycle status as discontinued or limited availability may apply. Validate package type SC-70-4L and threshold voltage accuracy against datasheet specifications before integration.

Selection Notes

Select this component for applications requiring precise voltage supervision with manual reset capability. Ensure the 2.2V threshold aligns with the monitored supply rail. Consider the 7µA quiescent current for low-power designs. Verify thermal performance within the -40°C to +125°C operating range for environmental compatibility.

Part Context

Part of the MAX6467/MAX6468 family of microprocessor supervisory circuits designed to improve system reliability compared to traditional manual reset circuits. Manufactured by Maxim Integrated, now part of Analog Devices Inc., these devices offer factory-trimmed thresholds for various supply voltages.
