ADM6326-31ARTZ-R7

Supervisors Overview

The ADM6326-31ARTZ-R7 is a single-channel voltage supervisor manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed reset threshold of 3.1 V. The device utilizes a push-pull output configuration with an active-low signal, ensuring robust drive capability for downstream logic. It incorporates a typical reset timeout delay of 100 ms to prevent false triggering during power-up transients. Packaged in a compact SOT-23-3 surface-mount footprint, the component supports industrial temperature ranges from -40°C to +85°C, making it suitable for space-constrained applications requiring reliable power management.

Supervisors Feature Summary

• Provides a fixed 3.1 V reset threshold for precise power monitoring
• Features a push-pull active-low output stage for strong logic interfacing
• Includes a standard 100 ms reset timeout to ensure stable power-up sequencing

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-operated devices requiring low-power monitoring
• Industrial control systems needing reliable reset signals

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the 3.1 V threshold aligns with system requirements. Check for RoHS compliance status and lead-free certification as per regional regulations. Confirm availability through authorized distributors, as stock levels may vary.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold is required for single-supply monitoring. The push-pull output is advantageous over open-drain types for driving higher capacitive loads or faster switching speeds. Consider the 100 ms timeout duration relative to the target system's power-up ramp time to avoid nuisance resets. Evaluate the SOT-23-3 package size against available PCB real estate constraints.
