ADM6348-44ARTZ-R7

Supervisors Overview

The ADM6348-44ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.62 V to 5.5 V and features a fixed threshold voltage of 4.38 V for precise monitoring. The device provides an active-low open-drain output with a typical reset timeout period of 185 ms. Designed for surface-mount applications, it utilizes a compact SOT-23-3 package. The component supports an operating temperature range from -40°C to +85°C and consumes minimal quiescent current, making it suitable for battery-powered systems requiring reliable power supervision.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated applications
• Fixed threshold voltage ensures accurate power monitoring
• Active-low open-drain output compatible with various logic families

• Microprocessor system supervision in embedded controllers
• Consumer electronics with strict size limitations

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the 4.38 V threshold matches the target system requirements. Check current availability status as distribution channels may vary. Ensure compatibility with existing PCB footprint and soldering processes before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.38 V threshold is required for system supervision. Consider the active-low open-drain output configuration for interface compatibility. Evaluate the 185 ms reset timeout against the target processor's startup time requirements. Verify that the SOT-23-3 package dimensions fit the available board space constraints.

Supervisors Part Context

This part belongs to the ADM6348 series of ultralow power reset circuits. It shares the same functional architecture and package style as other variants in the family, differing primarily in threshold voltage settings. The series is designed for general-purpose power supervision in portable and industrial applications where low current consumption is critical.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different threshold voltages if the 4.38 V setting is not mandatory. Cross-reference with ADM6326 or ADM6346 series parts for similar functionality, ensuring output type and timeout periods are compatible.
