ADM6348-42ARTZ-R7

Supervisors Overview

The ADM6348-42ARTZ-R7 is a supervisory voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features an active-low open-drain output. The device monitors a single input with a threshold voltage of 4.2 V. It includes a reset delay time of 185 ms and consumes a typical supply current of 500 nA. The component is housed in a SOT-23-3 package and supports surface mount installation.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Active-low open-drain reset output configuration
• Compact three-lead SOT-23 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Embedded microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against official Analog Devices documentation to confirm pinout, tolerance, and tape-and-reel specifications. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure the operating temperature range meets your system requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 4.2 V threshold is required for system monitoring. The open-drain output allows flexibility in interfacing with various logic levels through external pull-up resistors. Consider the 185 ms reset delay duration relative to your processor startup time requirements. Evaluate the 500 nA quiescent current impact on overall system battery life.

Supervisors Part Context

This part belongs to the ADM6348 series of ultra-low power reset circuits from Analog Devices. The series offers various threshold voltages and output configurations. The ADM6348-42ARTZ-R7 specifically provides the 4.2 V threshold variant in a reel-packaged SOT-23-3 form factor designed for high-volume surface mount assembly processes.

Supervisors Replacement Considerations

Check Analog Devices datasheets for other ADM6348 variants with different thresholds or output types. Verify compatibility with existing PCB footprints if substituting with similar packages from other manufacturers.
