ADM6348-39ARTZ-R7

Supervisors Overview

The ADM6348-39ARTZ-R7 is an ultralow power, three-lead microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.9 V for monitoring a single input. The device provides an active-low open-drain output with a typical reset delay time of 20 µs. Packaged in a compact SOT-23-3 surface-mount case, it is designed for applications requiring minimal quiescent current and reliable system supervision without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated systems
• Active-low open-drain output for flexible interfacing
• Compact three-lead SOT-23 package for space-constrained designs

Supervisors Applications

• Microprocessor system supervision
• Battery-powered portable electronics
• Embedded control circuits requiring power-on reset

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the tape-and-reel packaging format and temperature grade. Confirm the 3.9 V threshold requirement matches the target supply rail. Check current availability status as distribution channels may vary. Ensure ESD handling procedures are followed during surface-mount assembly. Validate RoHS compliance documentation for regulatory requirements.

Supervisors Selection Notes

Select this component when a fixed 3.9 V supervision threshold is required for low-voltage digital logic. The open-drain output necessitates an external pull-up resistor; ensure the resistor value aligns with the desired rise time and bus capacitance. Consider the 20 µs reset delay for timing-sensitive initialization sequences. Verify that the SOT-23-3 footprint fits the PCB layout constraints compared to larger packages.

Supervisors Part Context

This part belongs to the ADM6348 family of ultralow power reset circuits from Analog Devices. The family shares common architectural features but varies by threshold voltage and output type. The ADM6348 specifically denotes the open-drain output variant, distinguishing it from push-pull counterparts like the ADM6346. The -R7 suffix indicates reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different threshold voltages (e.g., ADM6348-33ARTZ-R7 for 3.3 V) if the supply rail differs. Cross-family replacements like the ADM6326 series offer similar functionality but may have different output structures or reset delays. Verify pinout compatibility before substitution.
