ADM6346-40ARTZ-R7

Supervisors Overview

The ADM6346-40ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.0 V. The device provides a push-pull output in a 3-lead SOT-23 package. Key electrical parameters include a reset delay time of 20 µs and a maximum supply current of 1 µA. It supports one monitored input without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultralow power consumption with 1 µA supply current
• Push-pull output configuration for robust drive capability
• Fixed threshold voltage monitoring for precise supervision
• Compact 3-lead SOT-23 surface-mount packaging

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered portable devices
• Handheld instruments
• Wearable electronics

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or official Analog Devices channels. Confirm the specific suffix ARTZ-R7 matches required tape-and-reel packaging specifications. Check for obsolescence status as this part may be discontinued. Ensure RoHS compliance documentation aligns with regional regulatory requirements before final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.0 V threshold is required for system supervision. The push-pull output eliminates the need for external pull-up resistors, simplifying PCB layout. Consider the ultralow quiescent current for battery-sensitive applications. Verify that the SOT-23-3 package fits the available board space constraints.

Supervisors Part Context

This device belongs to the ADM6346 family of ultralow power supervisors. It shares functional similarities with other variants in the series but differs in threshold voltage and output type. The ADM6348 series offers open-drain outputs, while other ADM6346 variants provide different voltage thresholds. All share the same compact footprint and low-power architecture.

Supervisors Replacement Considerations

Direct substitutes include other ADM6346 variants with adjusted threshold voltages if the 4.0 V level is not critical. Cross-reference with ADM6348 series for open-drain alternatives. Verify pin compatibility and electrical characteristics before substitution.
