ADM6346-39ARTZ-R7

Supervisors Overview

The ADM6346-39ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 3.9 V. The device provides a push-pull output and includes a reset delay time of 20 µs. Packaged in a compact SOT-23-3 form factor, it supports surface mount installation and functions across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors system power supply voltage against a fixed threshold
• Generates active-low or active-high reset signals via push-pull output
• Operates with ultra-low quiescent current for battery-powered applications

Supervisors Applications

• Microprocessor and microcontroller reset circuits
• Portable battery-operated equipment
• Consumer electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'R7' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 3.9 V threshold aligns precisely with the target system's logic voltage requirements before integration. Ensure compatibility with the SOT-23-3 footprint during PCB layout design.

Supervisors Selection Notes

Select this component when a fixed 3.9 V supervision level is required for low-power digital systems. The push-pull output capability allows direct interfacing with various logic families without additional pull-up resistors. Consider the 20 µs delay for timing-sensitive reset sequences in high-speed processors.

Supervisors Part Context

This part belongs to the ADM6346 series of ultra-low power reset circuits from Analog Devices. The series offers multiple threshold options within the same SOT-23-3 package, allowing designers to standardize on a single footprint while adjusting voltage monitoring parameters through different model suffixes.

Supervisors Replacement Considerations

Check for ADM6346 variants with different threshold voltages if system requirements change. Verify pinout compatibility with other SOT-23-3 supervisory ICs from Analog Devices or third-party manufacturers before substitution.
