MAX6336US22D2+T

Overview

The MAX6336US22D2+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage channel with a threshold of 2.2V and provides an active-low reset signal via a push-pull/totem pole output. The device features a minimum reset timeout of 20ms and operates within a temperature range of -40°C to 125°C. It is housed in a SOT-143-4 surface-mount package.

Feature Summary

• Monitors power supply voltage against a preset threshold to ensure system reliability
• Asserts reset signal when supply voltage declines below the specified level
• Maintains reset assertion for a defined timeout period after voltage recovery

Applications

• Microprocessor (µP) systems requiring power supervision
• Digital systems operating within 1.8V to 3.3V ranges
• Circuits needing elimination of external adjustment components

Procurement Notes

Verify component authenticity through authorized channels, as this part number is listed as discontinued by major distributors. Confirm final assembly marks and datasheet revisions match the specific batch requirements. Check for alternative sourcing options due to limited availability and potential obsolescence status affecting long-term supply chain stability.

Selection Notes

Select this component for applications requiring a simple, low-component-count reset solution with a fixed 2.2V threshold. Ensure the SOT-143-4 package fits the board layout constraints. Verify that the push-pull output type meets the driving requirements of the downstream logic inputs without additional buffering needs.

Part Context

This part belongs to the MAX6336 series of µP reset circuits designed for low-voltage digital systems. It shares functional similarities with the MAX6332 and MAX6333 but differs in output polarity and drive configuration. The series aims to reduce cost and board space by integrating monitoring functions into a compact surface-mount package.
