MAX6335US20D3+T

Overview

The MAX6335US20D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage supply with a threshold of 2.0V and features an active-low, open-drain output. The device provides a minimum reset timeout of 280ms and operates within a temperature range of -40°C to +125°C. Packaged in a SOT-143-4 surface-mount case, it supports manual reset functionality.

Feature Summary

• Monitors power supply voltage against a preset threshold
• Provides debounced manual-reset input capability
• Features active-low open-drain reset output

Applications

• Microprocessor (µP) systems
• Digital control circuits
• Battery-powered devices

Procurement Notes

Verify the specific suffix D3 for the 2.0V threshold variant when sourcing. Confirm RoHS compliance status (+ suffix). Check current availability as this component may be subject to limited supply or discontinuation notices from the manufacturer.

Selection Notes

Select this part for applications requiring low-voltage supervision in compact designs. Ensure the open-drain output configuration matches the system logic requirements. Verify that the 2.0V threshold aligns with the monitored rail's minimum operating voltage.

Part Context

Part of the MAX6335/MAX6336/MAX6337 family of ultra-low-voltage, low-power µP reset circuits designed to increase reliability by eliminating external components.

Replacement Considerations

Consider MAX6335US20D2+T for similar specifications with different reset timeout characteristics.
