MAX6314US47D2

Supervisors Overview

The MAX6314US47D2 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed reset threshold voltage of 4.70V and an active-low, bidirectional RESET output compatible with processors like the 68HC11. The device includes a debounced manual reset input and provides a 40ms reset timeout period after the supply voltage rises above the threshold or manual reset is deasserted. It operates within a supply voltage range up to 5.5V and functions across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional reset inputs
• Debounced manual reset input for user-initiated system resets
• Fixed 4.70V reset threshold voltage ensures precise power monitoring
• Integrated 40ms reset timeout period eliminates external timing components

Supervisors Applications

• Microprocessor (µP) power supply supervision
• Digital system reset control
• Battery-powered equipment monitoring

Supervisors Procurement Notes

Verify RoHS compliance status as datasheets indicate variations between leaded and lead-free versions. Confirm package type is SOT-143-4. Ensure the specific suffix matches the required threshold voltage and lead-free specifications for your design.

Supervisors Selection Notes

Select this component when a fixed 4.70V threshold is required for bidirectional microprocessor interfaces. It is suitable for applications needing integrated manual reset functionality without external debounce circuits. Consider thermal operating limits of -40°C to +85°C during selection.

Supervisors Part Context

Part of the MAX6314 family of µP supervisory circuits. Variants differ by reset threshold voltage (e.g., 3.08V, 4.38V, 4.63V). Manufactured by Maxim Integrated, now part of Analog Devices Inc. Designed for cost-effective, reliable power management in embedded systems.

Supervisors Replacement Considerations

Check for exact threshold voltage match (4.70V). Verify bidirectional output compatibility with target processor. Confirm package pinout alignment if substituting with other MAX6314 variants or competitor supervisors.
