MAX6315US43D3+T

Supervisors Overview

The MAX6315US43D3+T is a uPower supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.3 V with an overvoltage threshold of 4.38 V. The device provides an active low, open-drain output and includes a manual reset input. It has a reset delay time of 200 ms and consumes only 5 µA of operating supply current. Accuracy is specified at 1.8%. The component is housed in a compact SOT-143-4 package and supports surface mount installation.

Supervisors Feature Summary

• Provides precise voltage supervision with factory-set thresholds for reliable system monitoring
• Features ultra-low power consumption suitable for battery-operated applications
• Includes a manual reset input for user-initiated system control

Supervisors Applications

• Portable electronic devices requiring extended battery life

• Consumer electronics with strict space constraints

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions. Check for obsolescence notices as this series may have limited availability. Ensure packaging details match project requirements for surface mount assembly processes.

Supervisors Selection Notes

Select this part when a fixed 4.3 V threshold is required for single-supervision applications. Consider the SOT-143-4 package for space-limited designs. Verify that the open-drain output configuration aligns with the target logic interface. Evaluate the 5 µA quiescent current against total system power budgets.

Supervisors Part Context

This component belongs to the MAX6315 family of microprocessor supervisory circuits designed by Maxim Integrated. These devices are engineered to monitor power supplies in digital systems, ensuring reliable operation by asserting a reset signal when voltages fall outside specified limits. The family emphasizes low power and small form factors for portable applications.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts maintain identical threshold voltages and package dimensions. Verify compatibility with existing board layouts and electrical characteristics before implementation.
