ADM6348-35ARTZ-R7

Supervisors Overview

The ADM6348-35ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides a reset signal when the supply voltage drops below a precise threshold of 3.5 V. The device features an open-drain output type and operates within a maximum supply voltage of 5.5 V. It has a reset delay time of 185 ms and consumes a typical operating supply current of 500 nA. The component is housed in a 3-lead SOT-23 package suitable for surface mount installation.

Supervisors Feature Summary

• Ultralow power consumption with typical supply current of 500 nA
• Precise monitoring of 3.5 V supply rail threshold
• Built-in glitch filtering to ignore negative VCC transients
• Open-drain reset output compatible with various logic levels

Supervisors Applications

• Microprocessor reset circuits requiring low standby current
• Battery-powered portable electronic devices
• Systems monitoring 3.3 V or 3.5 V power rails
• Embedded systems needing reliable power supervision

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix ARTZ-R7 matches project requirements for package, temperature range, and tape/reel configuration. Check lifecycle status as this part may be discontinued or subject to last-time buy notices. Ensure ESD handling procedures are followed during storage and assembly. Review the official datasheet for any recent product change notifications affecting pinout or electrical characteristics.

Supervisors Selection Notes

Select this component when a fixed 3.5 V threshold is required for power supervision. Consider the open-drain output if level shifting or wired-OR configurations are needed. Evaluate the 185 ms reset delay against system startup timing requirements. Compare against the ADM6346 series if push-pull outputs or different thresholds are preferred. Verify that the 500 nA quiescent current fits within the overall system power budget constraints.

Supervisors Part Context

This part belongs to the ADM6348 family of ultralow power supervisors from Analog Devices. It shares the same SOT-23-3 package and functional architecture as other variants like the ADM6348-34ARTZ-R7 but differs in its specific trip point. The family is designed for applications where minimal power consumption is critical. Variants offer different threshold voltages ranging from 2.2 V to 4.63 V to accommodate various standard supply rails.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different threshold voltages such as ADM6348-34ARTZ-R7 (3.4 V) or ADM6348-41ARTZ-R7 (4.1 V), provided the voltage level adjustment meets system requirements. Cross-family replacements from other manufacturers require verification of pin compatibility, output type, and reset delay characteristics.
