MAX6315US46D3+T

Supervisors Overview

The MAX6315US46D3+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single power supply input and asserts an active-low, open-drain reset signal when the voltage falls below a fixed threshold of 4.63V. The device features a manual reset input and a typical reset timeout period of 200ms. It operates within a supply voltage range up to 5.5V and supports an extended industrial temperature range from -40°C to +125°C. The component is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors and digital systems upon power-up or brown-out conditions
• Includes a debounced manual reset input for user-initiated system resets
• Features an open-drain output compatible with various logic families
• Designed with low supply current consumption suitable for portable applications

Supervisors Applications

• Monitoring power supplies in microprocessor-based systems
• Brown-out detection circuits in digital electronics
• Portable equipment requiring low standby current
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify the exact threshold voltage and package type against the official datasheet before integration. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the ordering suffix matches the required tape-and-reel packaging specifications for automated assembly processes.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for system supervision. The open-drain output allows for flexible interfacing with different logic levels. Consider the SOT-143-4 package size for space-constrained designs. Verify that the manual reset feature meets the system's operational requirements for user intervention.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits designed for monitoring single power rails. It shares functional similarities with other members of the family but differs in its specific factory-programmed threshold voltage. The series is characterized by low power consumption and robust performance across wide temperature ranges.

Supervisors Replacement Considerations

Direct substitutes include other MAX6315 variants with different thresholds, such as MAX6315US45D3+T (4.5V) or MAX6315US38D3+T (3.8V), provided the threshold adjustment aligns with the application needs. Cross-series replacements like the MAX6314 require verification of bidirectional output compatibility.
