MAX6315US46D3-T

Supervisors Overview

The MAX6315US46D3-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed threshold voltage of 4.6V and an overvoltage threshold of 4.68V. The device provides an active-low, open-drain reset output with a manual reset input and a typical reset delay time of 200ms. Operating from a supply voltage up to 5.5V, it draws only 5µA of quiescent current. The component is housed in a compact SOT-143-4 surface-mount package and operates within a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation through a dedicated manual reset input for controlled initialization sequences.
• Ensures stable operation under varying power conditions by monitoring the supply voltage against precise threshold levels.
• Minimizes power consumption in battery-operated applications through ultra-low quiescent current characteristics.

Supervisors Applications

• Microprocessor and digital system power supply monitoring
• Battery-powered portable electronic devices
• Industrial control systems requiring voltage supervision

Supervisors Procurement Notes

Verify component authenticity due to potential availability issues. Confirm that the specific suffix corresponds to the tape-and-reel packaging format. Check for lead-free compliance status as indicated in official documentation. Ensure the part number matches the exact voltage threshold requirements for your design. Validate that the manufacturer has not discontinued this specific variant before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-channel voltage supervision. Consider the SOT-143-4 package for space-constrained printed circuit board layouts. Evaluate the 200ms reset delay to ensure compatibility with target processor startup times. Verify that the open-drain output interface aligns with the receiving logic circuitry requirements.
