MAX6315US44D1+T

Supervisors Overview

The MAX6315US44D1+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features an open-drain output and manual reset capability within a compact SOT-143-4 package. The device operates with a supply voltage range up to 5.5V and includes a fixed threshold voltage of 4.4V. It provides a reset delay time of 200ms and maintains high accuracy of 1.8%. The component supports a wide operating temperature range from -40°C to +125°C and consumes only 5µA of quiescent current.

Supervisors Feature Summary

• Monitors single power supply input for under-voltage conditions
• Provides active-low open-drain reset signal output
• Includes manual reset pin for system control
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring

Supervisors Procurement Notes

Verify RoHS compliance status as documentation indicates detailed verification is required. Confirm lead-free status and packaging type (Reel, Cut Tape, or MouseReel) against specific project requirements. Check current availability as the component may be subject to obsolescence or discontinuation by the manufacturer. Ensure the ordering suffix matches the desired tolerance and package variant.

Supervisors Selection Notes

Select this part when a fixed 4.4V threshold is required for single-supervision applications. The SOT-143-4 package offers space efficiency for dense PCB layouts. Consider the 200ms reset delay and 1.8% accuracy for timing-sensitive designs. Verify that the open-drain output configuration aligns with the downstream logic interface requirements.
