MAX6467XS32D3/V+T

Overview

The MAX6467XS32D3/V+T is a microprocessor supervisory reset circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 3.2V. The device features an edge-triggered, one-shot manual reset function and operates within a temperature range of -40°C to +125°C. It utilizes an SC-70-4 surface-mount package with an active-low, open-drain output type.

Feature Summary

• Monitors single power-supply voltages from +1.8V to +5.0V
• Features edge-triggered, one-shot manual reset function
• Provides active-low, open-drain reset output

Applications

• Microprocessor (µP) supervisory circuits
• Power supply support circuits
• Embedded system reset management

Procurement Notes

Verify the specific suffix 'V' against official datasheets, as standard listings typically use 'D3'. Confirm RoHS compliance status for the '+T' tape-and-reel variant. Check current availability as distribution channels may list this component as limited or discontinued. Ensure the 3.2V threshold matches the design requirements before procurement.

Selection Notes

Select this component when a fixed 3.2V threshold is required for single-channel voltage monitoring. The SC-70-4 package suits space-constrained designs. Verify that the active-low open-drain output aligns with the target microprocessor's reset input logic. Consider the -40°C to +125°C operating range for industrial applications.

Part Context

This part belongs to the MAX6467 series of microprocessor supervisory circuits. The series includes variants with different threshold voltages and packages. The MAX6467 family is designed to provide reliable reset signals for digital systems, ensuring proper initialization and protection against brown-out conditions.

Replacement Considerations

Check for direct substitutes within the MAX6467 series with matching 3.2V thresholds. Verify pin compatibility with SC-70-4 packages. Cross-reference with MAX6468 variants if dual-channel monitoring is needed, though electrical characteristics must be compared carefully.
