MAX6315US29D4-T

Supervisors Overview

The MAX6315US29D4-T is a voltage 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 2.93 V. The device provides an active-low, open-drain reset output with a manual reset input capability. It is housed in a compact SOT-143-4 surface-mount package. The component supports an operating temperature range from -40°C to +125°C and consumes a typical quiescent current of 5 µA.

Supervisors Feature Summary

• Provides reliable system reset generation when monitored supply voltage drops below the specified threshold.
• Includes a manual reset input pin allowing external control over the reset state independent of voltage levels.
• Features low power consumption suitable for battery-operated applications requiring extended operational life.

Supervisors Applications

• Monitoring microprocessor power supplies in embedded systems
• Ensuring stable operation in portable electronic devices
• Protecting memory circuits during power-down sequences

Supervisors Procurement Notes

Verify the exact suffix D4 against official datasheets to confirm the specific threshold voltage variant, as suffixes denote different trip points. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the SOT-143-4 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a precise 2.93 V threshold is required for single-supply monitoring. Consider the open-drain output compatibility with your system logic levels. Evaluate the manual reset feature necessity for your design. Compare the 5 µA quiescent current against other family members if ultra-low power is critical. Verify the industrial temperature range meets your environmental constraints.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits designed for monitoring single power supplies. It complements other variants in the family that offer different threshold voltages and output configurations. The series is characterized by low power consumption and small package options, targeting space-constrained and battery-powered applications across various industries.

Supervisors Replacement Considerations

Check for MAX6315US29D3+T or MAX6315US29D4+T for lead-free equivalents. Verify functional compatibility with MAX6315USxxDx+T variants offering similar thresholds. Consult Analog Devices for direct cross-references ensuring identical electrical characteristics and pinouts.
