MAX6467XS16D3-T

Overview

The MAX6467XS16D3-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 1.575V. The device features an edge-triggered, one-shot manual reset function that ensures the microprocessor enters reset mode for a fixed timeout period only. It operates with a maximum supply voltage of 5.5V and has a reset delay time of 225 ms. The component draws a typical operating supply current of 7 uA and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Edge-triggered, one-shot manual reset function prevents continuous reset assertion during held manual buttons
• Factory-trimmed threshold voltage ensures accurate power-supply monitoring without external components
• Low quiescent current design supports battery-powered applications requiring extended operational life

Applications

• Microprocessor (µP) supervisory circuits in embedded systems
• Power-supply monitoring for portable electronic devices
• System reliability enhancement in industrial control units

Procurement Notes

Verify the exact suffix configuration against the official datasheet, as variations may indicate different package types or thermal ratings. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or discontinuation notices. Ensure the ordering information matches the required threshold voltage and output type specifications for your application design.

Selection Notes

Select this component when a simple, low-power supervisory circuit is needed for single-rail monitoring. The MAX6467 series offers factory-trimmed thresholds eliminating the need for external resistors. Consider the SC-70-4 package size for space-constrained designs. Verify that the 225 ms reset delay aligns with your microprocessor startup requirements and that the active-low open-drain output is compatible with your system logic levels.

Part Context

The MAX6467 belongs to a family of microprocessor supervisory circuits designed to improve system reliability compared to traditional manual reset circuits. These devices monitor single power-supply voltages and provide reset signals based on preset thresholds. The series includes various threshold options to accommodate different voltage rails commonly used in digital electronics.
