ADM6348-41ARTZ-R7

Supervisors Overview

The ADM6348-41ARTZ-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 drops below the specified threshold. The device features an active-low open-drain output, ensuring compatibility with various logic families. It operates within a supply voltage range up to 5.5 V and functions across a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-3 surface-mount package, designed for space-constrained applications requiring reliable power supervision.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated systems
• Active-low open-drain reset output for flexible logic interfacing
• Compact three-lead SOT-23 package for minimal board space usage

Supervisors Applications

• Microprocessor system power supervision
• Portable electronic devices requiring low standby current
• Telecommunications equipment voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the tape-and-reel packaging format and temperature grade. Confirm the threshold voltage corresponds to the required system rail, as the ADM6348 series offers multiple fixed options. Check current availability status, as this specific part number may be subject to lifecycle changes or discontinuation. Ensure RoHS compliance documentation is available if required for your manufacturing process.

Supervisors Selection Notes

Select this component when an active-low open-drain output is preferred over push-pull configurations. The ADM6348 series is distinct from the ADM6346 series, which typically uses push-pull outputs. Verify that the fixed threshold voltage matches the target supply rail without requiring external resistors. Consider the SOT-23-3 footprint constraints during PCB layout design to ensure adequate clearance for the open-drain pull-up resistor.

Supervisors Part Context

This part belongs to the ADM6348 family of ultralow power supervisors from Analog Devices. These devices are engineered to protect sensitive circuitry such as microprocessors and memory elements from under-voltage conditions. The family shares common architectural features but differs in output type and threshold voltage options, allowing designers to tailor the supervision circuit to specific application requirements.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different threshold voltages (e.g., ADM6348-34ARTZ-R7) if the voltage level can be adjusted. Cross-family replacements like the ADM6346 series require accounting for the push-pull output difference. Verify pinout compatibility before substituting with generic supervisor ICs.
