MAX6467XS29D3

Overview

The MAX6467XS29D3+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 2.925V. The device features an active-low, open-drain output and includes an edge-triggered, one-shot manual reset function. 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 reset delay time of 225ms.

Feature Summary

• Edge-triggered, one-shot manual reset function ensures fixed timeout period for reset mode entry
• Monitors single power-supply voltages from +1.8V to +5.0V with factory-trimmed threshold accuracy
• Active-low, open-drain reset output compatible with various logic families

Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Reset generation for digital circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Ensure proper handling procedures are followed due to surface-mount packaging sensitivity. Cross-reference datasheet specifications against application requirements to validate suitability for target operating conditions.

Selection Notes

Select this component when a single-channel voltage supervisor with manual reset capability is required. Consider the 2.925V threshold specifically for applications requiring precise low-voltage detection within the 1.8V-5.0V range. Evaluate thermal performance and package constraints for SC-70-4 footprint compatibility before integration into design schematics.

Part Context

Part of the MAX6467/MAX6468 family of microprocessor supervisory circuits designed to improve system reliability compared to traditional manual reset designs. These devices provide essential protection against brown-out conditions and ensure proper initialization sequences for connected processors and memory components in complex electronic systems.

Replacement Considerations

MAX6467XS29D3+T is the complete part number including tape-and-reel suffix. Verify exact threshold voltage matching when substituting similar supervisory ICs from other manufacturers.
