ADM6328-22ARTZ-R7

Supervisors Overview

The ADM6328-22ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It features a single monitored input with a threshold voltage of 2.2V and provides an active-low open-drain output. The device operates within a supply voltage range up to 5.5V and includes a fixed reset delay time of 100ms. Packaged in a compact SOT-23-3 surface-mount case, it is designed for applications requiring minimal quiescent current consumption.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated systems
• Active-low open-drain output configuration
• Fixed 100ms reset timeout period
• Compact three-lead SOT-23 package

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation systems
• Microprocessor reset circuits in space-constrained designs
• Consumer electronics with strict power budget constraints

Supervisors Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when ordering. Confirm the 22 threshold voltage variant matches system requirements. Check current availability status as component lifecycle may vary. Ensure ESD handling procedures are followed during surface mount assembly. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when an active-low open-drain output is required rather than push-pull. Choose the 2.2V threshold specifically for monitoring lower voltage rails. Consider the SOT-23-3 footprint for board space optimization. Evaluate the 100ms fixed delay against system startup timing needs. Compare quiescent current specifications against other supervisor ICs for efficiency.

Supervisors Part Context

This part belongs to the ADM6328 family of ultralow power reset circuits from Analog Devices. The series offers various threshold voltages and output configurations. The ADM6328 variant specifically provides an open-drain output. Other family members include push-pull output options like the ADM6346. All share similar low power characteristics and SOT-23 packaging.

Supervisors Replacement Considerations

Direct substitutes include other ADM6328 variants with different threshold voltages such as ADM6328-29ARTZ-R7 or ADM6328-28ARTZ. Cross-family replacements like ADM6346 require checking output type differences between open-drain and push-pull. Verify pin compatibility and electrical parameters before substitution.
