ADM6328-26ARTZ-R7

Supervisors Overview

The ADM6328-26ARTZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.63 V. The device provides an open-drain or open-collector output with a manual reset capability. It supports a watchdog timer function and includes a reset timeout delay of 200 ms minimum. The component is housed in a compact SOT-23-3 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside voltage supervision.
• Provides manual reset functionality via an external input pin.
• Features ultra-low power consumption suitable for battery-operated applications.
• Offers flexible output configuration with open-drain or open-collector options.

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Voltage monitoring for battery-powered portable devices
• Industrial control systems requiring watchdog protection

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 to confirm the tape and reel packaging format and the exact 2.63V threshold variant. Ensure compatibility with the target PCB footprint for the SOT-23-3 package. Confirm that the open-drain output logic levels align with the connected microcontroller or processor input requirements. Check for RoHS compliance status if required by project specifications.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer are needed in a minimal footprint. The 2.63V threshold is appropriate for monitoring 3.3V logic rails. Consider the manual reset feature if hardware intervention is required during debugging. The low operating current makes it ideal for energy-constrained designs compared to standard supervisors.

Supervisors Part Context

This part belongs to the ADM6328 series of ultra-low power reset circuits from Analog Devices. The series is characterized by its small SOT-23-3 package and integrated watchdog functionality. Variants within the series differ primarily by their voltage thresholds and output types, allowing designers to tailor the supervision parameters to specific rail voltages without changing the physical form factor.

Supervisors Replacement Considerations

Cross-reference with ADM6328-29ARTZ-R7 for higher threshold applications. Verify functional equivalence with ADM6326 series parts, noting differences in output type (push-pull vs. open-drain) and the absence of a watchdog timer in the simpler ADM6326 variants.
