ADM6346-34ARTZ-R7

Supervisors Overview

The ADM6346-34ARTZ-R7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features a fixed threshold voltage of 3.4 V for monitoring power rails. The device provides a push-pull output capable of sourcing or sinking current, ensuring robust reset signal integrity. It includes a programmable reset delay time ranging from 1 ms to 500 ms to accommodate various system startup requirements. Packaged in a compact SOT-23-3 surface-mount case, it supports operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides automatic power-on reset and manual reset functionality via dedicated input pin
• Features low quiescent current consumption suitable for battery-powered applications
• Offers flexible reset delay timing to manage complex system initialization sequences

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Portable electronic devices requiring low-power monitoring
• Industrial control systems with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Confirm availability status as distribution channels may list obsolete or limited-stock variants. Ensure compatibility with existing PCB footprint and thermal management strategies before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.4 V threshold is required for system voltage monitoring. Consider the push-pull output capability if driving long traces or multiple loads without external pull-up resistors. Evaluate the programmable delay feature against system startup constraints to ensure adequate power stabilization time before releasing the reset signal.

Supervisors Part Context

This part belongs to the ADM6346 series of ultra-low power supervisory circuits. It shares functional similarities with other members like the ADM6348 but differs in output structure and specific threshold options. The series is designed for applications demanding minimal standby current while maintaining reliable reset generation under varying supply conditions.

Supervisors Replacement Considerations

Direct substitutes include ADM6346-33ARTZ-R7 (3.3 V threshold) or ADM6346-30ARTZ-R7 (3.0 V threshold) if voltage levels differ. Cross-family alternatives such as MAX6346 require verification of output drive strength and delay timing specifications.
