MAX6314US46D3-T

Supervisors Overview

The MAX6314US46D3-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional RESET output compatible with microprocessors like the 68HC11 and includes a debounced manual reset input. The device asserts a reset signal when the supply voltage falls below a preset threshold of 4.63V or upon manual assertion, maintaining the state for a timeout period after voltage recovery. It operates within a supply range up to 5.5V, consumes 5µA of current, and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11.
• Integrated debounced manual reset input allows for user-initiated system resets without external components.
• Low quiescent current consumption supports battery-powered applications while maintaining reliable voltage supervision.

Supervisors Applications

• Microprocessor (µP) and digital system power supply monitoring
• Systems requiring compatibility with bidirectional reset inputs like the 68HC11
• Portable devices utilizing low-power voltage supervision

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation, as variations exist between leaded and lead-free versions. Confirm package type and temperature range specifications directly from the datasheet to ensure compatibility with your design requirements before procurement.

Supervisors Selection Notes

Select this component for applications requiring a bidirectional interface with legacy microprocessors. Ensure the 4.63V threshold aligns with the target supply voltage. Verify that the SOT-143 package fits the board layout constraints and that the operating temperature range meets environmental conditions.

Supervisors Part Context

This part belongs to the MAX6314 series of µP reset circuits manufactured by Maxim Integrated, now part of Analog Devices. The series focuses on providing reliable power supervision with minimal external component count, specifically addressing the needs of systems requiring bidirectional reset signaling capabilities.

Supervisors Replacement Considerations

Check for MAX6314US46D3+T for lead-free compliance if required. Other MAX6314 variants with different thresholds may serve as functional substitutes if the voltage level differs.
