MAX6335US22D3+T

Overview

The MAX6335US22D3+T is a microprocessor supervisory circuit designed for 1.8V to 3.3V systems. It monitors the VCC supply voltage and asserts an active-high reset signal when the voltage drops below the 2.2V threshold or upon manual reset assertion. The device operates with a minimum supply voltage of 0.7V and features a push-pull output. It includes a debounced manual-reset input and guarantees correct state down to 0.7V.

Feature Summary

• Monitors power supplies in low-voltage microprocessor and digital systems
• Features a debounced manual-reset input for user-initiated control
• Asserts reset signal during under-voltage conditions or manual activation
• Maintains correct output state at ultra-low supply voltages

Applications

• Microprocessor (µP) system supervision
• Digital system power monitoring
• Battery-powered device reset circuits

Procurement Notes

Verify the manufacturer part number against official Analog Devices documentation to confirm the specific suffix configuration. Check current availability status as distribution channels may list obsolete or discontinued variants. Ensure the ordering information matches the required output polarity and package type specified in the datasheet before finalizing procurement.

Selection Notes

Select this component for applications requiring an active-high reset output from the MAX633x family. Compare against MAX6336 and MAX6337 variants if active-low outputs are preferred. Verify that the 2.2V threshold aligns with the target system's brown-out requirements. Confirm compatibility with the SOT-143-4 package constraints for space-critical designs.

Part Context

This part belongs to the MAX6335/MAX6336/MAX6337 series of 4-pin, ultra-low-voltage, low-power µP reset circuits. These devices eliminate external components by integrating precision comparators and timeout timers into a compact SOT-143 package. The series is designed to increase circuit reliability while reducing cost in portable and battery-operated electronics.
