ADM6346-38ARTZ-R7

Supervisors Overview

The ADM6346-38ARTZ-R7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 3.8 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, designed for surface mount installation. The component supports a single monitored input without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Compact three-lead SOT-23 surface-mount package design
• Push-pull output stage providing active drive capability

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems with strict power management needs
• Microprocessor reset circuits in space-constrained PCB layouts

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the tape-and-reel packaging format and temperature grade. Confirm the 3.8 V threshold voltage matches the system requirements. Check for RoHS compliance status as indicated in official documentation. Ensure the SOT-23-3 footprint aligns with the target PCB design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 3.8 V threshold is required for system supervision. The push-pull output is preferred over open-drain types for faster switching speeds. Consider the ultra-low power characteristics if battery life is a critical design parameter. Verify that the 20 µs reset delay meets the timing requirements of the connected microprocessor or logic components.

Supervisors Part Context

This part belongs to the ADM6346 family of ultralow power reset circuits from Analog Devices. The series offers various fixed threshold voltages to accommodate different supply rails. These devices are engineered for simple, reliable supervision of power supplies in embedded systems where minimal component count and low quiescent current are essential design priorities.

Supervisors Replacement Considerations

Cross-reference with other ADM6346 variants sharing the same SOT-23-3 package and push-pull output. Verify that substitute parts maintain the 3.8 V threshold tolerance and 20 µs reset delay specifications. Ensure compatibility with the existing PCB footprint and thermal management requirements during replacement.
