MAX6314US46D2

Supervisors Overview

The MAX6314US46D2 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed reset threshold voltage of 4.63V and provides a bidirectional RESET output compatible with 68HC11 processors. The device includes a debounced manual reset input and ensures system reliability by asserting reset when supply voltage falls below the preset threshold or upon manual activation. It operates within a specified temperature range and utilizes an SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to 68HC11 and similar microprocessors
• Debounced manual reset input for user-initiated system control
• Eliminates need for external components through integrated supervision logic

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system reset control
• 68HC11-based embedded designs

Supervisors Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm RoHS compliance markings on physical units, as suffixes indicate lead-free variants. Check current availability status with authorized distributors, as supply constraints may affect procurement timelines. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Supervisors Selection Notes

Select this part when a bidirectional reset interface is required for legacy microcontrollers like the 68HC11. The fixed 4.63V threshold suits applications where this specific voltage level aligns with the target system's operating requirements. Consider the SOT-143-4 package size for space-constrained surface-mount designs requiring minimal external component count.

Supervisors Part Context

This component belongs to the MAX6314 family of supervisory circuits from Maxim Integrated, now part of Analog Devices. The series offers various fixed threshold voltages to accommodate different supply rails while maintaining consistent bidirectional output functionality and low-power operation characteristics across the product line.

Supervisors Replacement Considerations

Compatible substitutes include other MAX6314 variants with different threshold voltages (e.g., MAX6314US26D3, MAX6314US33D1) if the supply voltage differs. Verify pin compatibility and bidirectional output support when selecting alternatives.
