MAX6315US31D4-T

Supervisors Overview

The MAX6315US31D4-T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.08 V with an overvoltage threshold of 3.14 V. The device provides an active low, open-drain output and includes manual reset functionality. It has a reset delay time of 200 ms and consumes 5 uA of operating current. Accuracy is specified at 1.8%. The component is housed in a SOT-143-4 package and supports operation from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with fixed threshold detection for system reliability
• Features manual reset capability allowing user-initiated system recovery
• Delivers active low open-drain output signal compatible with digital logic interfaces

Supervisors Applications

• Portable equipment power management
• Battery-powered systems supervision
• Microcontroller reset circuits

Supervisors Procurement Notes

Verify the specific suffix D4 against official datasheets to confirm the exact threshold voltage variant, as suffixes often denote different trip points within the same family. Ensure the SOT-143-4 package matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-channel voltage supervision. Consider the 5 uA quiescent current for battery-sensitive designs. Verify that the open-drain output configuration suits the downstream logic levels. Ensure the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the MAX6315 series of ultra-low-power microprocessor reset circuits. The series offers various threshold voltages and packages. The US31 designation indicates the specific 3.08 V threshold version. The D4 suffix typically denotes the package type or tape/reel configuration in Maxim's nomenclature, specifically associated with the SOT-143 form factor.

Supervisors Replacement Considerations

Check for MAX6315US31D3+T if a different packaging format is needed but identical electrical characteristics are required. Verify compatibility with other MAX6315 variants sharing the same threshold voltage.
