MAX6467US46D3+

Overview

The MAX6467US46D3+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 4.625V. The device features an edge-triggered, one-shot manual reset function to ensure proper system initialization. It operates within a temperature range of -40°C to +125°C and consumes a maximum quiescent current of 7µA.

Feature Summary

• Monitors single power-supply voltages from +1.8V to +5.0V
• Asserts reset when supply voltage drops below preset threshold
• Includes edge-triggered, one-shot manual reset function

Applications

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

Procurement Notes

Verify the specific suffix 'D3+T' indicates tape-and-reel packaging configuration. Confirm availability status as some distributors list this part as limited supply or discontinued. Ensure the 4.625V threshold matches the application requirement. Check RoHS compliance documentation for lead-free certification details before final procurement.

Selection Notes

Select this component when a fixed 4.625V threshold is required for single-rail monitoring. Consider the 7µA quiescent current for low-power designs. Verify that the SC-70-4 package fits the PCB layout constraints. Ensure the manual reset input is compatible with the system's control logic interface requirements.

Part Context

The MAX6467 series belongs to Maxim Integrated's family of microprocessor supervisory circuits. These devices are designed to provide reliable reset signals for digital systems. The US46 variant specifically targets applications requiring a 4.625V trip point. The series supports both active-low open-drain outputs and manual reset inputs for flexible system integration.

FAQ

What is the reset output type?

The MAX6467US46D3+T provides an active-low, open-drain reset output.

Does the device include a watchdog timer?

No, the MAX6467US46D3+T does not include a built-in watchdog timer; it functions solely as a voltage supervisor.
