ADM6346-43ARTZ-R7

Supervisors Overview

The ADM6346-43ARTZ-R7 is an ultralow power microprocessor reset 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 4.3 V. The device utilizes a push-pull output configuration and provides a reset delay time of 20 µs. It is housed in a compact 3-lead SOT-23 package, suitable for surface mount applications. The component supports a single monitored input channel without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultralow power consumption design for battery-operated systems
• Fixed threshold voltage monitoring for precise supervision
• Push-pull output driver for robust signal integrity

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered electronic devices
• Portable instrumentation supervision

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 4.3V threshold matches system requirements. Check current availability status as distribution may vary. Ensure RoHS compliance documentation is obtained from authorized channels. Validate pinout compatibility with existing PCB footprints before integration.

Supervisors Selection Notes

Select this component when a fixed 4.3V supervision level is required for low-power microprocessor resets. The push-pull output eliminates the need for external pull-up resistors. Consider the SOT-23-3 package size for space-constrained designs. Verify that the 20 µs delay meets the target processor's timing specifications.

Supervisors Part Context

This part belongs to the ADM6346 family of ultralow power reset circuits. It shares the same package and basic architecture with variants offering different threshold voltages. The series is designed for applications requiring minimal quiescent current and reliable system supervision in portable electronics.

Supervisors Replacement Considerations

Substitute parts must match the 4.3V threshold and SOT-23-3 package. Verify equivalent push-pull output characteristics and supply voltage limits. Cross-reference functional compatibility with the target microprocessor reset requirements.
