ADM6328-31ARTZ-R7

Supervisors Overview

The ADM6328-31ARTZ-R7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It monitors a single voltage channel with a threshold of 3.1V. The device features an open-drain active-low output and provides a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +85°C and is housed in a SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact three-lead SOT-23 package design
• Guaranteed valid reset output down to 1V supply voltage

Supervisors Applications

• Portable electronic devices requiring low standby current
• Industrial control systems operating in harsh environments
• Battery-powered instrumentation and sensors

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the open-drain output configuration and tape-and-reel packaging format. Ensure the 3.1V threshold aligns with the target system's voltage requirements. Confirm RoHS compliance status and check for any specific handling instructions related to the SOT-23-3 package during assembly.

Supervisors Selection Notes

Select this component when a simple, low-power supervisor is needed for a single rail. The fixed 3.1V threshold limits flexibility compared to adjustable models. Consider the open-drain output requirement for pull-up resistor integration. Evaluate if the 100ms timeout meets the system's startup timing constraints.

Supervisors Part Context

This part belongs to the ADM6328 family of ultra-low power reset circuits. It shares the same package and general functionality as variants like the ADM6326 but differs in output type and threshold voltage. The series is designed for applications where power efficiency and small footprint are critical priorities.

Supervisors Replacement Considerations

Direct substitutes include other ADM6328 variants with different thresholds (e.g., ADM6328-28ARTZ-R7) or the ADM6326 series if push-pull output is acceptable. Verify pin compatibility and electrical specifications before substitution.

Supervisors FAQ
