MAX6467US42D3

Overview

The MAX6467US42D3 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. 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. This component utilizes an SOT-143-4 surface-mount package and operates within a temperature range of -40°C to +125°C.

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 active-low reset output when supply voltage falls below preset threshold

Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Manual reset circuit integration

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check current availability as this part may be subject to limited supply or discontinuation notices. Ensure the specific suffix matches required threshold voltage specifications before procurement.

Selection Notes

Select this component for applications requiring reliable microprocessor supervision with manual reset capabilities. Consider the fixed threshold voltage option corresponding to the '42' suffix. Evaluate the SOT-143-4 package size against board space constraints and verify operating temperature range compatibility with the target environment.

Part Context

The MAX6467 series belongs to Maxim Integrated's family of microprocessor supervisory circuits designed to enhance system reliability. These devices monitor power supplies and provide reset signals to ensure proper microprocessor initialization. The MAX6467 variant specifically offers a compact solution for single-channel voltage monitoring with integrated manual reset functionality.

Replacement Considerations

Consult official documentation for cross-reference data. Verify pinout compatibility and electrical parameter alignment with potential substitute components before implementation.
