ADM6326-22ARTZ-R7

Supervisors Overview

The ADM6326-22ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs. It features a fixed threshold voltage of 2.2 V and utilizes a push-pull output configuration. The device operates within a supply voltage range up to 5.5 V and provides a reset timeout of 100 ms minimum. It is housed in a surface-mount SOT-23-3 package and supports an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable power supply supervision with a fixed 2.2 V threshold for precise voltage monitoring.
• Features a push-pull output stage capable of driving loads directly without external pull-up resistors.
• Ensures system stability through a guaranteed minimum reset timeout period of 100 ms.

Supervisors Applications

• Monitoring microprocessor power rails in embedded systems
• Supervising battery-powered devices requiring low quiescent current
• Protecting logic circuits against under-voltage conditions

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 corresponds to the required tape and reel packaging format and temperature grade. Confirm that the 2.2 V threshold aligns with the target application's voltage requirements, as this variant differs from other threshold options within the ADM6326 family. Check component availability status as distribution may vary.

Supervisors Selection Notes

Select this component when a fixed 2.2 V supervision level is required for single-channel voltage monitoring. The push-pull output simplifies interface design compared to open-drain alternatives. Ensure the 100 ms reset delay meets the timing constraints of the controlled system. Compare against other ADM6326 variants if different thresholds or output types are needed.

Supervisors Part Context

This part belongs to the ADM6326 series of simple reset supervisors from Analog Devices. It shares the SOT-23-3 footprint and core architecture with other members of the family, differing primarily in threshold voltage and output configuration. It serves as a cost-effective solution for basic power management tasks where advanced features like watchdog timers are unnecessary.

Supervisors FAQ

Is the reset output active high or active low?

The reset output is active low, meaning it asserts a low signal when the monitored voltage falls below the threshold.

Does this device include a manual reset input?

No, the ADM6326-22ARTZ-R7 does not feature a manual reset input; it functions solely as a power-on reset supervisor.
