MAX6336US16D3

Overview

The MAX6336US16D3+T is a fixed-threshold supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 0.8V to 5.5V and features a fixed reset threshold voltage of 1.6V. The device provides a push-pull/totem pole output with an active-low reset signal. It includes a minimum reset timeout of 20ms and functions across an industrial temperature range of -40°C to +125°C. The component is housed in a compact SOT-143-4 package, designed for low-power microprocessor reset applications.

Feature Summary

• Provides automatic system reset upon power-up or brown-out events
• Features a fixed 1.6V threshold for precise voltage monitoring
• Delivers active-low reset signal via push-pull output stage

Applications

• Microcontroller-based embedded systems requiring reliable startup sequencing
• Portable battery-powered devices needing ultra-low-voltage supervision
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'D3' against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status (+) if lead-free operation is required. Check current availability as some variants may be discontinued or subject to limited supply constraints from Analog Devices.

Selection Notes

Select this part when a fixed 1.6V threshold is required for low-voltage logic families. Ensure the SOT-143-4 package fits the PCB layout constraints. Verify that the 20ms minimum timeout meets the system's initialization timing requirements without external components.

Part Context

This component belongs to the MAX6335-MAX6337 series of ultra-low-voltage, low-power microprocessor reset circuits. These devices are designed to replace discrete supervisor solutions, offering integrated threshold detection and timeout functionality in small surface-mount packages suitable for space-constrained designs.

Replacement Considerations

Cross-reference with MAX6336US16D3+T for identical specifications. Verify compatibility with MAX6336USxxD3 variants where xx denotes different threshold voltages.
