MAX6315US31D3-T

Supervisors Overview

The MAX6315US31D3-T is a CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features an active-low, open-drain reset output and supports manual reset functionality. The device operates within a supply voltage range of 1 V to 5.5 V with a threshold voltage of 3.08 V. It provides a fixed reset delay time of 200 ms and maintains high accuracy of 1.8%. The component functions reliably across an extended temperature range from -40°C to +125°C while consuming only 5 µA of operating supply current.

Supervisors Feature Summary

• Provides reliable system reset generation through monitoring of a single power supply input
• Supports manual reset capability for controlled system initialization or recovery
• Delivers an active-low, open-drain reset output compatible with various logic families
• Ensures stable operation across wide industrial temperature ranges with low power consumption

Supervisors Applications

• Microprocessor (µP) and digital system power supply supervision
• Battery-powered devices requiring low quiescent current monitoring
• Embedded systems needing manual reset control capabilities
• Industrial equipment operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix D3 against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the package type SOT-143-4 fits your PCB layout constraints. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the specific threshold voltage of 3.08 V with your target supply rail to ensure proper triggering behavior under all operating conditions.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset is required. The open-drain output allows flexible interfacing with different logic levels. Consider the 200 ms delay time for application timing requirements. Evaluate the 1.8% accuracy against your system tolerance needs. The wide operating temperature range makes it suitable for harsh environments where standard commercial grade parts may fail.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits from Maxim Integrated, now part of Analog Devices. The series offers various threshold voltages and packages to suit different monitoring needs. The US31 variant specifically targets applications requiring a 3.08 V threshold. These circuits are designed to replace discrete resistor networks and comparators, simplifying board design and reducing component count in power management architectures.

Supervisors Replacement Considerations

Check for MAX6315US31D3+T as a potential lead-free alternative if the original suffix indicates leaded composition. Verify functional equivalence with other MAX6315 variants having identical threshold voltages but different packages. Consult official substitution guides for any pin-compatible upgrades within the same supervisory family.
