MAX6326UR28+T

Supervisors Overview

The MAX6326UR28+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold of 2.8V. The device provides an active-low, open-drain output with a typical reset delay time of 200ms. It consumes ultra-low quiescent current of 500nA maximum and maintains accuracy within 1.5%. The component is housed in a compact SOT-23-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption with maximum quiescent current of 500nA
• Fixed 2.8V reset threshold for precise voltage monitoring
• Active-low open-drain output configuration
• Compact SOT-23-3 surface-mount packaging

Supervisors Applications

• Portable battery-powered equipment
• Microprocessor system supervision
• Battery chargers and adapters
• Consumer electronics

Supervisors Procurement Notes

Verify the specific suffix 'UR28' confirms the 2.8V threshold and SOT-23-3 package before ordering. Confirm RoHS compliance status as indicated in official documentation. Check manufacturer lifecycle status for availability constraints. Ensure ESD handling procedures are followed during installation.

Supervisors Selection Notes

Select this part when a fixed 2.8V threshold is required for single-supply monitoring. The open-drain output allows flexible interfacing with various logic levels. Consider the 500nA quiescent current for battery-sensitive designs. Verify that the 200ms reset delay meets system timing requirements.

Supervisors Part Context

This component belongs to the MAX6326/MAX6327/MAX6328 family of ultra-low-power reset circuits. The MAX6326 variant specifically offers fixed thresholds without manual reset inputs. It serves as a simple supervisor for microprocessors and memory devices requiring reliable power-on reset functionality.

Supervisors Replacement Considerations

Cross-reference with other MAX6326 variants having identical 2.8V thresholds and SOT-23-3 packages. Verify pinout compatibility and electrical specifications match before substitution.
