MAX6429MQUR+T

Overview

The MAX6429MQUR+T is a low-power single-level battery monitor manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1V to 6V and features a fixed threshold voltage of 2.944V. The device draws a typical operating current of 3.5µA and supports an SOT-23-3 surface-mount package. It functions as a supervisory circuit with a push-pull output, designed for monitoring input voltages in portable applications.

Feature Summary

• Provides precise supervision of battery or system voltage levels
• Features a factory-trimmed threshold for accurate detection
• Includes a minimum timeout period to ensure valid logic states
• Operates efficiently with ultra-low quiescent current consumption

Applications

• Portable electronic devices requiring battery level monitoring
• Handheld instruments needing power management supervision
• Battery-powered systems utilizing microprocessors
• Consumer electronics with limited power budgets

Procurement Notes

Verify the specific suffix 'MQUR' against official manufacturer documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through the latest datasheet revision. Check for any obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when a fixed threshold voltage near 2.94V is required for single-supply monitoring. Consider the SOT-23-3 package size constraints and the need for a push-pull output driver. Evaluate the 3.5µA current draw against strict power budget limitations. Compare against adjustable threshold alternatives if flexibility is needed.

Part Context

This part belongs to the MAX6461-MAX6466 family of low-power voltage supervisors. These devices are designed for simple reset or power-reset applications. They offer various threshold options and output configurations to suit different system requirements while maintaining low power consumption.

Replacement Considerations

Compatible substitutes include other parts from the MAX6461-MAX6466 series with matching threshold voltages and output types. Verify package compatibility and electrical specifications before substitution.
