MAX6314US44D4+T

Supervisors Overview

The MAX6314US44D4+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional output compatible with processors like the 68HC11, eliminating external components. The device asserts a reset signal when the supply voltage falls below a preset threshold or upon manual reset assertion. Key parameters include a 4.4V threshold voltage, a 200ms reset timeout period, and operation within a specified temperature range.

Supervisors Feature Summary

• Bidirectional output interface for direct connection to microprocessors with bidirectional reset inputs
• Integrated debounced manual reset input for user-initiated system resets
• Eliminates need for external components through integrated monitoring and timing functions

Supervisors Applications

• Microprocessor power supply monitoring in digital systems
• Systems requiring compatibility with 68HC11 architecture
• Applications needing manual reset capability alongside automatic voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance markings on packaging. Check datasheet revisions for any functional updates. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Validate pinout compatibility with target PCB footprint.

Supervisors Selection Notes

Select this part when bidirectional reset signaling is required for specific microprocessor architectures. Consider the fixed 4.4V threshold against system voltage rails. Evaluate the 200ms timeout duration against processor startup requirements. Verify SOT-143-4 package suitability for space-constrained designs. Assess power consumption needs against the device's low-power specifications.

Supervisors Part Context

Part of the MAX6314 family of supervisory circuits from Maxim Integrated, now Analog Devices. This series focuses on reliable power monitoring with minimal external component count. The US suffix indicates the SOT-143-4 package variant. The +T denotes tape and reel packaging configuration for automated assembly processes.

Supervisors Replacement Considerations

Check MAX6314US44D4-T for identical electrical characteristics without lead-free certification. Verify MAX6314US33D1-T if a lower 3.3V threshold is acceptable. Confirm MAX6314US46D2+T offers similar functionality with a higher 4.63V threshold. Ensure substitute parts maintain bidirectional output compatibility.
