MAX6467XS26D7-T

Overview

The MAX6467XS26D7-T is a microprocessor supervisory reset circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power-supply voltage ranging from +1.8V to +5.0V and asserts a reset signal if the supply drops below its preset threshold of 2.768V. The device features an edge-triggered, one-shot manual reset function that ensures the processor enters reset mode for a fixed timeout period, even during continuous manual reset activation. 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 225ms reset delay time.

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 for direct interface with logic inputs

Applications

• Microprocessor (µP) supervisory circuits
• Critical healthcare applications requiring voltage monitoring
• Systems needing reliable reset generation under varying supply conditions

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential counterfeits. Confirm RoHS compliance status (+ suffix indicates lead-free) and check for obsolescence notices as this series may have limited availability. Ensure the SC-70-4 package matches your PCB footprint requirements before procurement.

Selection Notes

Select this part when a fixed 2.768V threshold is required for single-supply monitoring. Consider the MAX6468 variant if a different threshold voltage is needed, as the MAX6467 family offers various factory-trimmed options. Evaluate the SC-70-4 package size against board space constraints and verify thermal performance within the specified operating temperature range.

Part Context

The MAX6467 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 MAX6467XS26D7-T specifically targets applications requiring robust supervision in compact form factors.

Replacement Considerations

The MAX6468XS26D7-T is a functional substitute within the same family, offering identical electrical characteristics and pinout compatibility while maintaining the 2.768V threshold specification.
