MAX6315US49D3-T

Supervisors Overview

The MAX6315US49D3-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. Key electrical parameters include a threshold voltage of 4.9V, a maximum supply voltage of 5.5V, and a reset delay time of 200ms. The device operates within a temperature range of -40°C to +125°C with an accuracy of 1.8%. It consumes only 5µA of quiescent current and is housed in a compact SOT-143-4 package.

Supervisors Feature Summary

• Monitors a single voltage supply channel for under-voltage conditions
• Provides active-low open-drain reset signal output
• Includes manual reset input functionality
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Microprocessor system power supply monitoring
• Digital system voltage supervision
• Battery-powered device power management

Supervisors Procurement Notes

Verify the specific suffix D3 indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official documentation as lead-free variants exist. Check current lifecycle status as Maxim Integrated products may face obsolescence. Ensure the 4.9V threshold matches the target application requirements precisely before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.9V threshold is required for single-channel monitoring. The SOT-143-4 package suits space-constrained designs. Consider the 200ms reset delay for system startup timing. Verify compatibility with the open-drain output interface of the monitored microprocessor or logic circuit.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits from Analog Devices/Maxim Integrated. The series offers various threshold voltages and packages. The US49 variant specifically targets 4.9V monitoring applications. It complements other MAX6315 models like the US45D3-T which share similar functional architectures but differ in threshold settings.

Supervisors Replacement Considerations

Direct substitutes include MAX6315US49D3+T (lead-free version) and MAX6315US49D3-T. Cross-reference with MAX6315US49D3 for non-tape versions. Ensure pinout compatibility with SOT-143-4 footprint.
