ADM6346-46ARTZ-R7

Supervisors Overview

The ADM6346-46ARTZ-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 4.63 V. The device provides an active-low push-pull output with a typical reset delay time of 20 µs. Packaged in a compact 3-lead SOT-23 format, it is designed for applications requiring minimal quiescent current and reliable system supervision.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated systems
• Active-low push-pull output driver capability
• Fixed threshold voltage monitoring without external components
• Compact 3-lead SOT-23 surface-mount package

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation and sensors
• Microprocessor system supervision in embedded controllers
• Voltage monitoring in space-constrained PCB designs

Supervisors Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging configuration when ordering. Confirm the 46 series designation corresponds to the 4.63 V threshold requirement for your application. Ensure compatibility with SOT-23-3 footprint during layout. Check current availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for system supervision. The push-pull output allows direct interfacing with digital logic without pull-up resistors. Consider the 20 µs reset delay for timing-sensitive applications. Verify that the 5.5 V maximum input rating exceeds your system's peak voltage.

Supervisors Part Context

This part belongs to the ADM6346 family of ultralow power supervisors from Analog Devices. The family includes variants with different threshold voltages, such as the ADM6346-42ARTZ-R7 (4.2 V) and ADM6346-44ARTZ-R7 (4.4 V). All share the same SOT-23-3 package and functional architecture, differing primarily in their trip points.

Supervisors Replacement Considerations

Direct substitutes include other ADM6346 variants with adjusted thresholds like ADM6346-44ARTZ-R7 or ADM6346-42ARTZ-R7 if voltage levels permit. Cross-brand replacements require matching SOT-23-3 pinout, push-pull output type, and comparable quiescent current specifications.
