ADM6348-36ARTZ-R7

Supervisors Overview

The ADM6348-36ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor reset applications. It operates within a supply voltage range up to 5.5 V and features an active-low open-drain output. The device monitors a single input with a fixed threshold voltage of 3.6 V, providing a reset delay time of 185 ms. It functions reliably across a temperature range of -40°C to +85°C and is housed in a compact 3-lead SOT-23 surface-mount package.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for specific supply rails
• Active-low open-drain output configuration
• Built-in glitch suppression to prevent false resets

Supervisors Applications

• Microprocessor reset circuits
• Portable electronic devices
• Telecommunications equipment
• Battery-powered instrumentation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential availability from secondary markets like Rochester Electronics. Confirm the specific suffix R7 indicates reel packaging. Check current lifecycle status as some variants may be discontinued or subject to long lead times. Ensure compatibility with existing PCB footprint and electrical requirements before procurement.

Supervisors Selection Notes

Select this part when a fixed 3.6 V threshold is required for system supervision. Compare against the ADM6346 series if push-pull outputs are preferred instead of open-drain. Consider the 185 ms reset timeout duration against system startup requirements. Verify that the ultra-low quiescent current meets strict power budget constraints for portable designs.

Supervisors Part Context

This component belongs to the ADM6348 family of ultralow power supervisors. It shares the SOT-23-3 package and general architecture with variants offering different threshold voltages such as 2.5 V, 3 V, 3.3 V, and 4.0 V. The family provides cost-effective protection for sensitive circuitry in space-constrained applications requiring minimal standby current.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different thresholds (e.g., ADM6348-33ARTZ-R7) if voltage levels differ. Cross-reference with ADM6346 series for similar functionality but note the output type difference between open-drain and push-pull configurations.
