MAX6315US35D3-T

Supervisors Overview

The MAX6315US35D3-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.5 V with an overvoltage threshold of 3.58 V. The device provides an active-low, open-drain reset output with a manual reset input and a 200 ms reset delay time. It consumes only 5 µA of operating supply current and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-143-4 surface-mount format, it offers 1.8% accuracy for precise voltage supervision.

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and lead times prior to ordering. Ensure the specific suffix matches design requirements as variants exist within the series. Check for obsolescence notices or lifecycle changes that may impact long-term supply stability.

Supervisors Selection Notes

Select this part when a fixed 3.5 V threshold is required for single-channel voltage monitoring. Consider the SOT-143-4 package for space-constrained designs. Evaluate the 200 ms delay against system startup timing needs. Compare against other MAX6315 variants if different threshold voltages or package options are necessary for the specific application.

Supervisors Part Context

This component belongs to the MAX6315 family of uP supervisory circuits manufactured by Analog Devices Inc./Maxim Integrated. The series offers various threshold voltages and packaging options to suit diverse monitoring requirements.
