MAX6315US47D4-T

Supervisors Overview

The MAX6315US47D4-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in µP and digital systems. It features a single voltage channel with a fixed threshold of 4.7V. The device provides an active-low, open-drain reset output with a manual reset input capability. It operates within a supply voltage range up to 5.5V and includes a typical reset delay time of 200 ms. The component is housed in a compact SOT-143-4 package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

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

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Battery-powered equipment power management

Supervisors Procurement Notes

Verify the exact suffix D4 against the manufacturer's latest documentation to confirm the specific threshold voltage variant. Confirm RoHS compliance status and lead-free certification details directly with Analog Devices or authorized distributors. Check for obsolescence notices as this series may have discontinued variants. Ensure the SOT-143-4 package availability matches your assembly requirements.

Supervisors Selection Notes

Select this component when a fixed 4.7V threshold is required for single-channel supervision. Consider the open-drain output compatibility with your system logic levels. Evaluate the 200 ms reset delay against your system startup timing requirements. Verify that the SOT-143-4 package fits your PCB layout constraints compared to other available packages in the MAX6315 family.

Supervisors Part Context

This part belongs to the MAX6315 family of low-power CMOS supervisors manufactured by Analog Devices/Maxim Integrated. The family offers various threshold voltages and package options to suit different monitoring needs. The US47D4 designation specifically indicates the 4.7V threshold variant in the SOT-143-4 surface-mount package.

Supervisors Replacement Considerations

Check for MAX6315US47D4+T which denotes lead-free compliance. Other MAX6315 variants with different thresholds (e.g., US26, US30) are functionally similar but have different trip points. Direct substitutes must match the 4.7V threshold and SOT-143-4 package.
