ADM6328-30ARTZ-R7

Supervisors Overview

The ADM6328-30ARTZ-R7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.5 V to 5.5 V and features a fixed threshold voltage of 3.0 V for monitoring input lines. The device provides an active low, open-drain reset output with a typical reset delay time of 200 ms. It is designed for ultra-low power consumption, drawing only 500 nA of quiescent current. The component supports a manual reset function and includes a watchdog timer option in the broader series, though specific configuration depends on the suffix. It is housed in a compact SOT-23-3 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power operation with 500 nA quiescent current for battery-sensitive applications
• Active low open-drain reset output compatible with various logic families
• Integrated manual reset capability allowing external control over system restart
• Compact SOT-23-3 surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Microcontroller and digital signal processor power supervision
• Embedded systems needing reliable brown-out protection
• Industrial control units operating in harsh thermal environments

Supervisors Procurement Notes

Verify the exact part number against official Analog Devices documentation to ensure correct threshold voltage and feature set. Confirm RoHS compliance status and manufacturing origin through authorized distributors. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly.

Supervisors Selection Notes

Select this component when a precise 3.0 V threshold is required for system monitoring. Consider the open-drain output topology if wired-OR configurations are necessary. Evaluate the 500 nA standby current against total system budget constraints. Compare alternative thresholds within the ADM6328 family if voltage levels differ. Verify that the manual reset pin functionality aligns with user interface requirements.

Supervisors Part Context

This component belongs to the ADM6328 series of voltage supervisors from Analog Devices. The series offers various threshold voltages and feature combinations including watchdog timers and manual resets. The 'ARTZ' suffix indicates a specific tape-and-reel packaging format with lead-free termination. The 'R7' designation typically refers to the reel quantity or packaging variant used by distributors.

Supervisors Replacement Considerations

Direct replacements include other ADM6328 variants with identical 3.0 V thresholds but different packaging or feature sets. Cross-reference with Maxim Integrated MAX6328 series parts for functional equivalence. Verify pin compatibility and electrical specifications before substituting. Ensure any alternative maintains the same open-drain output structure and reset delay characteristics.
