MAX6326XR26

Supervisors Overview

The MAX6326XR26+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides an active-low, open-drain reset output with a typical reset delay time of 185 ms. Designed for surface-mount installation in SC-70-3 packages, it consumes only 500 nA of operating supply current. The component supports an industrial temperature range from -40°C to +85°C and lacks manual reset or watchdog timer functionalities.

Supervisors Feature Summary

• Fixed factory-set reset threshold at 2.63 V
• Active-low open-drain reset output configuration
• Compact SC-70-3 surface-mount package

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-operated portable devices
• Consumer electronics power management
• Industrial control system supervision

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with SC-70-3 footprint requirements during design-in. Check current availability status as distribution may vary by region. Validate that the specific threshold voltage meets system requirements before finalizing selection.

Supervisors Selection Notes

Select this component when a low-power, single-supervisor solution is required for voltages near 2.63 V. The open-drain output allows flexibility in interfacing with various logic families. Consider the 185 ms timeout period against system startup requirements. Verify that the 500 nA quiescent current aligns with battery life expectations. Ensure the SC-70-3 package size fits within the available PCB area constraints.

Supervisors Part Context

This device belongs to the MAX6326X series of ultra-low-power microprocessor reset circuits. It is designed to monitor a single power supply rail and assert a reset signal when the voltage drops below the specified threshold. The series offers various threshold options and package types to accommodate different design needs while maintaining low power consumption and high accuracy.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the MAX6326 family. Verify pinout and electrical characteristics match before replacing. No direct substitute part numbers are confirmed in the provided source material.
