ADM6346-42ARTZ-R7

Supervisors Overview

The ADM6346-42ARTZ-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 fixed threshold voltage of 4.2 V for power supervision. The device utilizes a SOT-23-3 surface-mount package and provides a push-pull output configuration. It includes a reset delay time of 20 µs and lacks manual reset, watchdog timer, or battery backup switch functionalities. The component supports an operating temperature range starting from -40°C.

Supervisors Feature Summary

• Ultra-low power consumption design suitable for battery-operated applications
• Push-pull output stage providing active drive capability without external pull-up resistors
• Compact three-lead SOT-23 package optimized for space-constrained PCB layouts

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-powered instrumentation systems
• Embedded microprocessor reset circuits in compact modules

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm current availability status as distribution channels may list this part as obsolete or limited stock. Ensure compatibility with existing PCB footprints for SOT-23-3 packages during procurement planning.

Supervisors Selection Notes

Select this component when a fixed 4.2 V supervision threshold is required for system power rails. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the ultra-low power characteristic for applications where standby current minimization is critical for battery life extension.

Supervisors Part Context

This part belongs to the ADM6346 series of supervisory circuits from Analog Devices. It shares the family's low-power architecture but differs in threshold voltage and output type from variants like the ADM6348. The ARTZ designation specifies the automotive-grade temperature range and SOT-23-3 packaging format.

Supervisors Replacement Considerations

Direct substitutes include other ADM6346 variants with different threshold voltages if the 4.2 V level is adjustable in the system design. Cross-reference with ADM6326 series for similar functionality, noting potential differences in reset delay times and output configurations.
