MAX6336US22D2+

Overview

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

Feature Summary

• Provides reliable power-on reset and manual reset functionality for microprocessor systems
• Features a push-pull output stage for robust drive capability
• Operates across an extended industrial temperature range

Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation reset circuits

Procurement Notes

Verify the specific suffix D2+T against official documentation, as this indicates tape-and-reel packaging. Confirm current lifecycle status, as distributor records indicate this part may be discontinued or inactive. Ensure compatibility with existing board layouts using the SOT-143-4 footprint before procurement.

Selection Notes

Select this component when a fixed 2.2V threshold is required for system supervision. The SOT-143-4 package offers a compact solution for space-constrained designs. Verify that the 20ms minimum timeout meets the target processor's startup requirements. Consider the active-low output polarity during interface design.

Part Context

This part belongs to the MAX6335-MAX6337 series of low-power reset supervisors. These devices are designed to monitor voltage levels in portable and battery-operated applications. The US22 variant specifically denotes the 2.2V threshold voltage setting within this family.

Replacement Considerations

Check for direct pin-compatible replacements within the MAX6336 series with different thresholds if voltage requirements change. Verify availability of alternative suppliers offering equivalent SOT-143-4 reset supervisors.
