MAX6314US30D4-T

Supervisors Overview

The MAX6314US30D4-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 processors 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 3V or upon manual assertion. It provides a minimum reset timeout period of 1.12 seconds after the voltage rises above the threshold. Packaged in a compact SOT-143-4 surface-mount case, it eliminates external components for cost-effective reliability.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input allows for user-initiated system resets
• Low-power CMOS construction ensures efficient operation in portable applications

Supervisors Applications

• Portable devices requiring simple power-on reset functionality
• Industrial control systems needing reliable power supervision
• Microprocessor-based digital systems monitoring single power supplies

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and pin alignment against SOT-143-4 specifications. Ensure compatibility with bidirectional reset logic levels in target designs. Check for lead-free compliance if required by specific manufacturing standards. Validate datasheet revisions for accurate electrical timing parameters before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for direct processor integration. Choose based on the fixed 3V threshold suitability for the target supply rail. Consider the 1.12s minimum timeout for adequate power stabilization periods. Evaluate the SOT-143-4 footprint constraints against available PCB space. Verify manual reset input requirements align with system control logic needs.

Supervisors Part Context

Part of the MAX6314 family of microprocessor supervisory circuits from Maxim Integrated. Designed specifically for applications requiring robust power monitoring without complex external circuitry. Shares common family features such as bidirectional output capability and manual reset functionality across various threshold variants.

Supervisors Replacement Considerations

Consider MAX6314US26D3+T for lower 2.63V threshold requirements. Evaluate MAX6314US33D1-T for 3.3V threshold compatibility. Verify MAX6314US46D2+T for higher voltage supervision needs. All substitutes maintain bidirectional output and manual reset features within the same package.
