MAX6315US29D1+T

Supervisors Overview

The MAX6315US29D1+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input with a fixed threshold of 2.9V and features an active-low, open-drain reset output. The device includes a manual reset input and operates within a supply voltage range up to 5.5V. It provides a reset delay time of 280ms and maintains high accuracy of 1.8%. Designed for surface-mount installation in SOT-143-4 packages, it supports an extended industrial temperature range from -40°C to +125°C while consuming only 5µA of operating current.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices as this series may be subject to discontinuation. Ensure packaging specifications match design requirements. Validate thermal performance within the specified operating temperature range during integration.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required for single-channel voltage monitoring. Choose the SOT-143-4 package for space-constrained designs. Opt for this part if manual reset functionality and open-drain output compatibility are necessary. Consider the 280ms reset delay and 1.8% accuracy for timing-sensitive applications. Verify that the 5.5V maximum supply voltage aligns with the target system's power rails.
