MAX6315US47D3+T

Supervisors Overview

The MAX6315US47D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 4.7V. The device provides an active low, open-drain reset output with a manual reset capability. It includes a typical reset delay time of 140ms minimum and maintains an accuracy of 1.8%. Designed for surface-mount installation, it utilizes a SOT-143-4 package. The component supports a maximum power dissipation of 320mW and functions reliably across an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides active low open-drain reset signal generation based on monitored supply voltage levels
• Includes manual reset input functionality for system control override
• Operates with low quiescent current suitable for battery-powered applications
• Features high accuracy voltage monitoring with specified tolerance limits

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-operated electronic devices requiring voltage monitoring
• Portable instrumentation systems
• Industrial control circuits needing reliable reset generation

Supervisors Procurement Notes

Verify the exact suffix D3+T against official Analog Devices documentation to confirm lead-free status and tape-and-reel packaging specifications. Confirm that the 4.7V threshold matches your design requirements precisely. Check for obsolescence notices as Maxim Integrated products may have lifecycle changes. Ensure compatibility with your PCB footprint for the SOT-143-4 package. Validate RoHS compliance through the manufacturer's current datasheet rather than distributor summaries.

Supervisors Selection Notes

Select this component when a fixed 4.7V threshold is required for single-channel voltage monitoring. Consider the SOT-143-4 package size constraints and the need for an open-drain output interface. Evaluate the 140ms minimum reset timeout against your system's startup requirements. Compare the 1.8% accuracy specification against your application's tolerance needs. Verify that the 1V to 5.5V input range covers your operational voltage spectrum.

Supervisors Part Context

This part belongs to the MAX6315 series of ultra-low-power supervisor circuits. The series offers various threshold voltages and package options. The US47 designation indicates the specific 4.7V threshold variant. The D3 suffix typically denotes the SOT-143 package style. The +T suffix confirms lead-free composition and reel packaging. This family is designed for embedded systems requiring reliable power management.

Supervisors Replacement Considerations

Check for MAX6315US47D3-T (non-plus) if lead-free status is not critical. Verify MAX6315US47D3+ without T suffix if cut-tape or tube packaging is preferred. Ensure any substitute maintains the 4.7V threshold and SOT-143-4 footprint. Confirm equivalent reset timeout characteristics and accuracy specifications.
