MAX6467XS26D3+T

Overview

The MAX6467XS26D3+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 2.625V. The device features an edge-triggered, one-shot manual reset function that ensures the microprocessor enters reset mode for a fixed timeout period of 225ms, even during continuously asserted manual resets. It operates with a maximum supply voltage of 5.5V and draws only 7µA of quiescent current. The circuit provides an active-low, open-drain output and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Edge-triggered, one-shot manual reset function prevents indefinite reset states
• Active-low, open-drain output configuration for flexible interfacing
• Low quiescent current consumption suitable for battery-powered applications

Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Battery-operated electronic devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details upon order confirmation. Ensure proper handling procedures are followed as the component is sensitive to electrostatic discharge. Review datasheet specifications thoroughly before integration to ensure compatibility with target system requirements.

Selection Notes

Select this component when a reliable, low-power supervisory circuit with manual reset capability is required for single-voltage monitoring. Consider the 225ms reset delay and 2.625V threshold against system timing and voltage stability needs. Evaluate package size and operating temperature range suitability for the intended application environment compared to alternative supervisory solutions.

Part Context

This part belongs to the MAX6467/MAX6468 series of microprocessor supervisory circuits designed for monitoring single power supplies. The MAX6467 variant specifically features an open-drain output, distinguishing it from push-pull output alternatives within the family. These circuits are engineered to enhance system reliability by providing precise voltage monitoring and controlled reset generation for digital logic components.

Replacement Considerations

Direct substitutes include other MAX6467 variants with different threshold voltages or output configurations, such as MAX6467XS25D3+T or MAX6467XS30D3+T. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers' parts to ensure functional equivalence.
