ADM6346-44ARTZ-R7

Supervisors Overview

The ADM6346-44ARTZ-R7 is a voltage monitor circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 4.4 V. The device provides a push-pull output with a reset delay time of 20 µs. It does not include manual reset, watchdog timer, or battery backup switch functions. The component is housed in an SOT-23-3 package for surface mount installation.

Supervisors Feature Summary

• Provides automatic system reset when monitored voltage drops below the specified threshold
• Features push-pull output driver for direct interface with digital logic
• Ultra-low power consumption suitable for battery-operated applications

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Microprocessor and microcontroller reset circuits
• Battery-powered systems monitoring voltage levels

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with manufacturer specifications to maintain reliability. Check for obsolescence status as this part may have limited production support.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for system supervision. Consider the SOT-23-3 package size for space-constrained designs. Verify that the 20 µs reset delay meets the timing requirements of the target logic family. Ensure the maximum supply voltage of 5.5 V aligns with the system power rail.

Supervisors Part Context

This part belongs to the ADM6346 series of ultra-low power reset circuits from Analog Devices. The series offers various threshold voltages to accommodate different supply rails. The ARTZ suffix indicates a specific tape and reel packaging configuration for automated assembly processes.

Supervisors Replacement Considerations

Check for ADM6346 variants with different threshold voltages if the 4.4 V level is unsuitable. Verify pin compatibility with existing PCB layouts before substituting.
