MAX6315US45D3+

Supervisors Overview

The MAX6315US45D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.5 V with an accuracy of 1.8%. The device provides an active low, open-drain output and includes manual reset functionality. It consumes 5 uA of operating current and offers a reset delay time of 200 ms. The component supports a maximum power dissipation of 320 mW and functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 4.5 V threshold and 1.8% accuracy for reliable system monitoring.
• Features an active low, open-drain output compatible with various logic families without requiring external pull-up resistors.
• Includes manual reset capability allowing users to initiate a reset cycle independently of voltage conditions.
• Operates with ultra-low quiescent current of 5 uA to minimize power consumption in battery-powered applications.

Supervisors Applications

• Portable electronic devices requiring extended battery life through low-power supervision
• Embedded systems needing reliable power-on reset sequences
• Industrial control units operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variations such as D3+T indicate specific packaging formats like tape and reel. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental certifications may vary by production batch. Ensure the selected part number matches the required threshold voltage and package type for your specific design implementation.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for single-channel voltage monitoring. Consider the open-drain output configuration if interfacing with different logic voltage levels. Evaluate the 200 ms reset delay against system startup requirements. The wide operating temperature range makes it suitable for harsh industrial environments where standard commercial grade parts may fail.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits designed for voltage supervision. It shares common characteristics with other members of the family, such as low power consumption and manual reset features, but differs in its specific threshold voltage setting. The SOT-143-4 package allows for compact surface-mount integration in space-constrained designs.

Supervisors Replacement Considerations

Direct substitutes include other MAX6315 variants with different threshold voltages, such as MAX6315US38D3+T for 3.8 V applications. Cross-family alternatives from Maxim Integrated offering similar open-drain outputs and manual reset capabilities should be evaluated based on pin compatibility and electrical specifications.
