MAX6467XS16D3

Overview

The MAX6467XS16D3 is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power-supply voltages within the range of 1.8 V to 5 V and features a fixed threshold voltage of 1.6 V. The device provides an active-low, open-drain reset output with a manual reset input capability. It operates on a single supply voltage up to 5.5 V and consumes low quiescent current. The component is housed in a compact SC-70-4 package and supports surface-mount installation. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides precise voltage supervision for microprocessors and memory systems
• Includes a debounced manual reset input for user-initiated system control
• Delivers an active-low open-drain reset signal upon power failure or brown-out conditions

Applications

• Microprocessor (MPU) supervisory circuits
• Portable battery-powered equipment
• Consumer electronics requiring low-power monitoring
• Industrial control systems

Procurement Notes

Verify the specific suffix 'XS16' confirms the 1.6 V threshold voltage against official datasheets. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for obsolescence notices or limited availability statuses directly from Analog Devices or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a fixed 1.6 V threshold is required for low-voltage logic monitoring. Ensure the open-drain output configuration matches the downstream circuit requirements. Verify that the SC-70-4 package dimensions fit the available PCB space. Consider the operating temperature range suitability for the intended environment.

Part Context

This part belongs to the MAX6467 series of microprocessor supervisory circuits. The series offers various threshold voltages and output configurations to accommodate different system designs.
