MAX6467XS16D3+T

Overview

The MAX6467XS16D3+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 an active-low, open-drain reset signal if the supply drops below its preset threshold of 1.625V. The device features a manual reset input and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum supply voltage of 5.5V, a typical quiescent current of 7µA, and a reset timeout of 225ms. It is housed in a SC-70-4 surface-mount package.

Feature Summary

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

Applications

• Microprocessor (MPU) supervisory circuits
• Power supply monitoring systems
• Embedded system reset management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times with suppliers, as availability may vary. Ensure the specific threshold voltage variant matches design requirements before procurement.

Selection Notes

Select this component for applications requiring precise monitoring of low-voltage rails. The fixed 1.625V threshold suits systems where the supply must remain above this level for stable operation. Consider the SC-70-4 package size for space-constrained designs.

Part Context

Part of the MAX6467/MAX6468 family of microprocessor supervisory circuits. These devices are designed to provide reliable reset signals for digital logic and microprocessors, ensuring proper system initialization and recovery from power faults.

Replacement Considerations

Check for exact threshold voltage match when substituting. Other variants in the MAX6467 series offer different fixed thresholds (e.g., XS21, XS23, XS27). Verify package compatibility and electrical specifications.
