ADM6346-37ARTZ-R7

Supervisors Overview

The ADM6346-37ARTZ-R7 is a voltage monitor circuit manufactured by Analog Devices Inc., designed for ultra-low power applications. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.7 V. The device utilizes a push-pull output configuration and provides a reset delay time of 20 µs. Packaged in a compact SOT-23-3 surface-mount format, it monitors a single input without manual reset or watchdog timer capabilities. The component supports operation across a temperature range extending down to -40°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Push-pull output interface for direct logic connection
• Compact three-terminal SOT-23 package design

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation systems
• Microprocessor supervisory circuits in embedded systems

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm availability status as distribution channels may list this item as discontinued or limited stock. Ensure the 3.7 V threshold matches system requirements before procurement. Check RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed 3.7 V supervision level is required with minimal quiescent current. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 20 µs delay for fast transient response needs. Verify thermal performance within the specified operating temperature range.

Supervisors Part Context

This part belongs to the ADM6346 series of microprocessor reset circuits from Analog Devices. The series offers various threshold voltages to accommodate different supply rails. The ARTZ designation typically indicates an automotive-grade or extended temperature variant depending on specific datasheet definitions, housed in the standard SOT-23-3 footprint common to this family.

Supervisors Replacement Considerations

Check for ADM6346 variants with different threshold voltages if system rail differs. Compare ADM6326 series for similar functionality but potentially different reset delays. Verify pinout compatibility with existing PCB layouts before substituting.
