MAX6326XR25-T

Supervisors Overview

The MAX6326XR25-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supply voltages and asserts a reset signal when the VCC supply declines below a factory-set threshold of 2.5V. The device operates within a voltage range of 1.0V to 5.5V and features a minimum power-on reset timeout period of 200ms. Designed for ultra-low-power applications, it consumes minimal current while providing reliable system supervision in digital environments.

Supervisors Feature Summary

• Monitors power-supply voltages and asserts reset when voltage drops below preset threshold
• Ultra-low-power design suitable for battery-operated systems
• Guaranteed valid resets down to 1.0V input voltage

Supervisors Applications

• Microprocessor system supervision
• Battery-powered portable electronics
• Digital control circuits requiring voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as ordering codes may vary. Confirm lead times and availability directly with authorized distributors, as stock levels fluctuate. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Supervisors Selection Notes

Select this component when a fixed 2.5V reset threshold is required for low-voltage digital systems. Consider the 200ms timeout period for power-on stability. Evaluate the SC70/SOT package constraints for PCB layout. Compare against adjustable threshold alternatives if precise voltage matching is not critical.

Supervisors Part Context

Part of the MAX6326 family of ultra-low-power reset circuits. Shares functional similarities with other MAX632x variants but differs in specific threshold voltages and timeout periods. Designed for compact embedded applications where space and power consumption are primary constraints.

Supervisors Replacement Considerations

Direct substitutes include MAX6326XR25+T or MAX6326XR25UT+T from the same manufacturer. Verify pinout compatibility and electrical specifications before substitution. Generic equivalents may lack the guaranteed 1.0V operation or specific timeout characteristics.
