ADM6346-45ARTZ-R7

Supervisors Overview

The ADM6346-45ARTZ-R7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.5 V. The device utilizes a push-pull output configuration and provides a typical reset delay time of 20 µs. Packaged in a compact 3-lead SOT-23 format, it is designed for ultra-low power applications with no manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Fixed threshold voltage monitoring for precise power supervision
• Push-pull output driver for robust signal integrity

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered instrumentation and sensors
• Microprocessor system power management

Supervisors Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when sourcing. Confirm the 4.5 V threshold matches the target supply rail requirements. Ensure compatibility with the SOT-23-3 footprint during PCB layout. Check for RoHS compliance status if required by regional regulations.

Supervisors Selection Notes

Select this component when a fixed 4.5 V supervision level is required without adjustable thresholds. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 20 µs delay for timing-sensitive reset sequences. Evaluate power budget constraints against the device's ultra-low quiescent current specifications.

Supervisors Part Context

This part belongs to the ADM6346 series of ultra-low power reset circuits. It shares the same package and basic architecture as variants with different threshold voltages, such as the ADM6346-42ARTZ-R7. The series is designed to replace larger, higher-power supervisor ICs in space-constrained designs.

Supervisors Replacement Considerations

Direct substitutes include other ADM6346 variants with similar threshold voltages, such as the ADM6346-42ARTZ-R7 or ADM6346-46ARTZ-R7, provided the threshold difference is acceptable. Verify pinout compatibility with the SOT-23-3 package before substitution.
