MAX6315US44D2+T

Supervisors Overview

The MAX6315US44D2+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed threshold voltage of 4.39 V and an overvoltage threshold of 4.47 V. The device provides an active-low, open-drain reset output with a manual reset input and a typical reset delay time of 200 ms. Operating from a supply voltage up to 5.5 V, it draws only 5 uA of quiescent current. Accuracy is specified at 1.8%, and it functions within a temperature range of -40°C to +125°C in a SOT-143-4 package.

Supervisors Feature Summary

• Provides reliable power supply monitoring for microprocessor and digital systems
• Features manual reset capability for system control flexibility
• Delivers active-low open-drain reset signal with defined delay timing
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Microprocessor power supply supervision
• Digital system voltage monitoring
• Battery-powered equipment reset circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status matches the '+T' suffix designation. Check manufacturing date codes against project lifecycle requirements as older batches may exist. Ensure storage conditions adhere to moisture sensitivity level specifications prior to assembly.

Supervisors Selection Notes

Select this part when a fixed 4.39 V threshold is required for single-channel monitoring. Consider the open-drain output compatibility with system logic levels. Evaluate the 200 ms reset delay against target system startup timing constraints. Verify that the SOT-143-4 package fits the available PCB footprint area.

Supervisors Part Context

This component belongs to the MAX6315 series of supervisory circuits from Analog Devices/Maxim Integrated. The series offers various threshold voltages and package options for different power monitoring needs. The US44 variant specifically targets applications requiring a 4.39 V trip point with manual reset functionality.

Supervisors Replacement Considerations

Cross-reference with MAX6315US44D2-T for non-RoHS versions. Verify pinout compatibility with other MAX6315 variants before substitution. Check if alternative thresholds meet system voltage requirements.
