MAX6335US16D3+T

Overview

The MAX6335US16D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage supply with a threshold of 1.6V and features a push-pull, totem pole output that asserts active high reset. The device provides a minimum reset timeout of 100ms 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
• Asserts reset signal when supply declines below threshold or on manual reset input
• Features debounced manual-reset input for user-initiated system restart

Applications

• Microprocessor (µP) systems requiring voltage supervision
• Digital systems operating at low voltages
• Circuits needing reliable power-on reset functionality

Procurement Notes

Verify the exact suffix D3 against the manufacturer's current part numbering guide to ensure compatibility with specific threshold and package variations. Confirm RoHS compliance status through official documentation as regulatory requirements may vary by region and production batch. Check for obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a simple, low-power reset circuit is required for 1.8V to 3.3V systems. The 1.6V threshold suits applications where the supply rail drops significantly below nominal levels. Ensure the active-high push-pull output aligns with the target microprocessor's reset pin requirements. Verify that the SOT-143-4 package fits the available PCB footprint constraints.

Part Context

The MAX6335 belongs to the MAX6335/MAX6336/MAX6337 family of ultra-low-voltage, low-power µP reset circuits. These devices are designed to increase circuit reliability and reduce cost by eliminating external components and adjustments. They perform a single function: asserting a reset signal whenever the VCC supply voltage declines below a preset threshold or when the manual-reset input is activated.
