MAX6326UR29-T

Supervisors Overview

The MAX6326UR29-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supply voltages and asserts an active-low, push-pull reset signal when the VCC supply declines below a preset threshold of 2.93V. The device maintains this state for at least 100ms after VCC rises above the threshold. It operates within a voltage range of 1V to 5.5V, consumes a maximum supply current of 1µA, and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low supply current consumption suitable for portable equipment
• Active-low push-pull reset output with 100ms minimum timeout
• Precision monitoring of standard power-supply voltages

Supervisors Applications

• Portable/battery-powered controllers
• Computers and power monitoring systems
• Intelligent instruments

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as 'T' typically indicates reel packaging while '+T' may denote RoHS compliance. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the ordering part number matches the specific threshold voltage and package variant required for the design.

Supervisors Selection Notes

Select this component for applications requiring low-power supervision of single-channel voltage rails. The fixed 2.93V threshold suits 3V logic systems. Consider the MAX6327 or MAX6328 if active-high or open-drain outputs are needed instead. Verify that the 100ms reset timeout meets system startup requirements.

Supervisors Part Context

This part belongs to the MAX6326/MAX6327/MAX6328 family of ultra-low-power SC70/SOT-23 reset circuits. These devices eliminate external components for 2.5V, 3V, 3.3V, and 5V powered circuits. The MAX6326 specifically provides an active-low push-pull output, distinguishing it from other variants in the series.
