MAX6314US28D2-T

Supervisors Overview

The MAX6314US28D2-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 68HC11 and similar microprocessors, eliminating the need for external components. The device provides a manual reset input and operates within a supply voltage range up to 5.5V. It includes a fixed reset timeout period of 200ms and maintains an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Manual reset input allows for user-initiated system resets
• Low-power CMOS construction ensures minimal supply current consumption
• Eliminates external components and adjustments through integrated supervision

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Systems requiring bidirectional reset compatibility such as 68HC11 architectures

Supervisors Procurement Notes

Verify the specific threshold voltage suffix corresponding to the required trip point, as the MAX6314 series offers multiple factory-set options. Confirm package availability and lead times directly with authorized distributors or Analog Devices, as stock levels fluctuate. Ensure the selected variant matches the thermal and electrical requirements of the target application environment before finalizing procurement orders.

Supervisors Selection Notes

Select this component when bidirectional reset signaling is required for direct interfacing with specific microprocessor families. Compare against open-drain variants if pull-up resistors are undesirable or if different output drive characteristics are needed. Verify that the fixed 200ms timeout meets the system's power-on stability requirements without additional external timing components.

Supervisors Part Context

This part belongs to the MAX6314 family of supervisory circuits manufactured by Maxim Integrated, now part of Analog Devices. The family focuses on providing reliable power management for microprocessor systems with minimal external component count. The US28D2 suffix indicates a specific threshold voltage setting and package configuration within this broader product line.

Supervisors Replacement Considerations

MAX6314US28D3+T: Similar bidirectional output but potentially different tolerance or revision. MAX6314US33D1-T: Different threshold voltage (3.3V). MAX6315US28D2-T: Open-drain output instead of bidirectional; requires different interface design.
