MAX6328XR26-T

Overview

The MAX6328XR26+T is a 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 output and includes a reset delay time of 185 ms. It consumes a typical operating supply current of 500 nA and supports overvoltage detection at 2.669 V. The component is housed in a 3-pin SC-70 package and functions across a temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Fixed threshold voltage monitoring for precise power supervision
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring extended battery life
• Microprocessor system power management
• Consumer electronics with limited power budgets

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as +T or + indicate specific tape-and-reel packaging configurations. Confirm RoHS compliance status through the latest datasheet revision. Ensure the supplier provides traceability to Analog Devices or Maxim Integrated authorized channels to guarantee component authenticity and quality standards.

Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-input voltage monitoring. Consider the SC-70 package dimensions for layout compatibility. Evaluate the 500 nA quiescent current against system power budgets. Verify that the 185 ms timeout meets the microprocessor startup requirements without manual reset functionality.

Part Context

This component belongs to the MAX6328X series of ultra-low-power microprocessor reset circuits. The series offers various threshold voltages and packages to accommodate different system voltage levels. The XR26 variant specifically targets applications needing a 2.63 V supervision level in a minimal footprint form factor.

Replacement Considerations

Check for other MAX6328 variants with identical 2.63 V thresholds and SC-70 packaging. Verify pinout compatibility before substitution. Ensure replacement parts maintain the same electrical characteristics and package dimensions.
