MAX6312UK29D3+T

Supervisors Overview

The MAX6312UK29D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 2.9V and operates within a supply voltage range up to 5.5V. The device provides one channel with an active low output type and includes a manual reset input function. It utilizes a 5-pin SOT-23 package, supports surface mount installation, and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors multiple power supply inputs for system integrity
• Includes manual reset input capability for user control
• Immune to short transients on monitored supply lines

Supervisors Applications

• Portable computers and battery-powered equipment
• Personal computer systems monitoring 5V and 3.3V rails
• Embedded control systems requiring multi-voltage supervision

Supervisors Procurement Notes

Verify the exact suffix against official Maxim Integrated documentation to confirm threshold voltage and timeout specifications. Ensure the component matches the lead-free RoHS compliance status indicated in the datasheet. Confirm package marking codes align with the SOT-23-5 physical dimensions. Cross-reference the manufacturer part number with Analog Devices records to validate authenticity and revision history before procurement.

Supervisors Selection Notes

Select this component when precise factory-set thresholds are required without external resistor programming. The fixed 2.9V threshold suits applications where specific voltage levels must be strictly maintained. Consider the small SOT-23 footprint for space-constrained portable designs. Verify that the single-channel configuration meets the monitoring requirements for the target power rails.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of microprocessor supervisory circuits. These devices are engineered for low supply current operation, making them suitable for portable applications. The series offers various factory-programmed reset thresholds in increments, ensuring compatibility with standard logic voltage levels while maintaining high accuracy over temperature ranges.

Supervisors Replacement Considerations

Consult the official datasheet for cross-reference options within the MAX63xx family. Verify pinout compatibility and electrical parameters such as reset delay times before substituting.
