MAX6467XS23D3+T

Overview

The MAX6467XS23D3+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 2.37V. The device features an edge-triggered, one-shot manual reset function that ensures the microprocessor enters reset mode for a fixed timeout period of 225 ms, even during continuously asserted manual resets. It operates within a temperature range of -40°C to +125°C, consumes 7 µA of quiescent current, and supports a maximum supply voltage of 5.5V. The component is housed in an SC-70-4 package.

Feature Summary

• Edge-triggered, one-shot manual reset function prevents indefinite reset states
• Monitors single power-supply voltages with factory-trimmed thresholds
• Asserts reset output when supply voltage falls below preset level
• Operates across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Check for obsolescence notices as availability may be limited. Ensure packaging specifications match design requirements. Validate datasheet revisions against production batches.

Selection Notes

Select this component when monitoring a single voltage rail between 1.8V and 5.0V is required. Choose based on the specific 2.37V threshold needed for the target application. Consider the SC-70-4 package size for space-constrained designs. Verify compatibility with the system's manual reset logic requirements.

Part Context

Part of the MAX6467/MAX6468 family of microprocessor supervisory circuits designed to improve system reliability compared to traditional manual reset circuits. These devices provide precise voltage monitoring with minimal quiescent current consumption, suitable for battery-powered and portable applications.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference threshold voltages and package types carefully. Verify functional equivalence before implementation.
