MAX6467XS16D3/V+T

Overview

The MAX6467XS16D3/V+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 1.6V. The device features an active-low, open-drain output with a manual reset function and a fixed reset delay time of 225 ms. It operates within a supply voltage range up to 5.5V and consumes a typical quiescent current of 7 uA. 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 without requiring external components for basic operation.

Feature Summary

• Monitors single power-supply voltages and asserts reset when voltage falls below the preset threshold
• Includes edge-triggered, one-shot manual reset function for system control
• Provides active-low, open-drain reset output compatible with various logic families
• Operates over an extended industrial temperature range from -40°C to +125°C

Applications

• Microprocessor (µP) supervisory circuits
• Portable equipment power management
• Battery-powered systems
• Consumer electronics

Procurement Notes

Verify the specific suffix 'V' against official documentation to confirm temperature grade or variant specifications, as standard listings may vary. Confirm RoHS compliance status through the manufacturer's certificate. Check current availability as distribution channels may report limited stock or discontinuation. Ensure the SC-70-4 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a fixed 1.6V threshold is required for monitoring low-voltage rails. The SC-70-4 package offers space efficiency for compact designs. Consider the 225 ms reset delay and 7 uA quiescent current for battery life optimization. Verify that the active-low open-drain output aligns with the target microprocessor's reset input requirements.

Part Context

The MAX6467 series belongs to Maxim Integrated's family of microprocessor supervisory circuits designed for reliable system reset generation. These devices are engineered to monitor power supplies and ensure proper initialization of digital logic. The MAX6467XS16D3/V+T specifically targets applications requiring precise voltage supervision in a minimal footprint, supporting both portable and industrial environments with robust performance characteristics.

Replacement Considerations

Cross-reference with other MAX6467 variants having different threshold voltages if the 1.6V setting is unsuitable. Verify pinout compatibility with alternative packages like SOT-143-4 if redesigning the layout. Consult the manufacturer's obsolescence notices for potential end-of-life status.
