ADM6321AX29ARJZ-R7

Supervisors Overview

The ADM6321AX29ARJZ-R7 is a single-channel supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 2.93 V. The device incorporates a watchdog timer with a typical timeout of 1.4 ms and provides an open-drain or push-pull active-low reset output. It is housed in a compact 5-lead SOT-23 package and is rated for operation over the industrial temperature range of -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system monitoring
• Provides manual reset input capability
• Offers configurable reset output stages including push-pull and open-drain options

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Industrial control unit monitoring

Supervisors Procurement Notes

Verify the specific suffix 'AX' against official Analog Devices documentation to confirm the exact threshold voltage and feature set, as variations exist within the ADM6321 family. Ensure the component matches the required reset output configuration and operating temperature range for the target application before finalizing procurement.

Supervisors Selection Notes

Select this component when a dedicated supervisor with integrated watchdog functionality is required in a space-constrained design. The SOT-23-5 package offers a small footprint suitable for portable or dense PCB layouts. Consider the fixed 2.93 V threshold and available output drive types to ensure compatibility with the downstream logic levels.

Supervisors Part Context

This part belongs to the ADM632x series of supervisory circuits from Analog Devices. The series is characterized by low power consumption and multiple reset timeout options. The ADM6321 variant specifically includes a manual reset input and watchdog timer, distinguishing it from simpler reset-only supervisors in the same product line.

Supervisors Replacement Considerations

Compatible substitutes include other ADM6321 variants with matching threshold voltages and output configurations, such as ADM6321AY29ARJZ-R7. Verify pinout compatibility and electrical specifications before substitution.
