MAX6326XR26-T

Supervisors Overview

The MAX6326XR26-T is a voltage supervisory circuit from the MAX6326U series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a fixed threshold of 2.63 V and an overvoltage threshold of 2.669 V. The device features an active-low, push-pull output and provides a reset delay time of 185 ms. It operates within a supply voltage range up to 5.5 V and maintains an accuracy of 1.5%. The component consumes 500 nA of operating current and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for digital systems with high accuracy
• Features ultra-low power consumption suitable for battery-operated applications
• Delivers a reliable active-low push-pull reset signal upon power failure

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Battery-powered portable electronics
• Consumer electronic devices requiring voltage supervision

Supervisors Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as +T or -TR indicate specific packaging configurations like cut tape or reel. Confirm RoHS compliance status and lead-free certification requirements with the supplier prior to ordering. Ensure the selected variant matches the required package type and thermal specifications for your design.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-channel voltage monitoring. The MAX6326XR26-T is appropriate for designs needing an active-low push-pull output without manual reset or watchdog timer functionality. Consider the 185 ms timeout period and 500 nA quiescent current when evaluating system power budgets and reset timing constraints.

Supervisors Part Context

This component belongs to the MAX6326/27/28 family of microprocessor supervisory circuits designed for low-voltage applications. These devices are engineered to monitor power-supply voltages while consuming minimal current. The MAX6326 variant specifically offers an active-low push-pull output, distinguishing it from open-drain or bidirectional alternatives in the broader product line.

Supervisors Replacement Considerations

The MAX6326UR26+T serves as a direct pin-compatible alternative within the same series, offering identical electrical characteristics but housed in an SOT-23-3 package instead of SC-70-3. Verify package dimensions and footprint compatibility before substitution.
