ADM6320CX29ARJZ-R7

Supervisors Overview

The ADM6320CX29ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc. housed in a 5-lead SOT-23 package. It monitors a single power supply input with a fixed reset threshold voltage of 2.93 V and an accuracy of 2.5%. The device features an open-drain active-low reset output, a manual reset input, and a watchdog timer. It operates within a supply voltage range up to 5.5 V and supports a reset delay time of 200 ms. The component functions reliably across an industrial temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection alongside voltage supervision
• Includes a dedicated manual reset input for user-initiated system control
• Provides an open-drain active-low reset output stage compatible with various logic families

Supervisors Applications

• Microprocessor systems requiring reliable power monitoring
• Controllers needing watchdog functionality
• Intelligent instruments demanding low-power supervision

Supervisors Procurement Notes

Verify the specific suffix 'CX' against official Analog Devices documentation to confirm the exact temperature grade and material composition. Ensure the order matches the required RoHS compliance status and packaging format. Cross-reference the part number with the manufacturer's current datasheet to validate availability and any recent design changes before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is appropriate for the target supply rail. The open-drain output requires an external pull-up resistor. Consider the 200 ms reset delay and available watchdog timeout options during system timing analysis. Verify that the SOT-23-5 package fits the mechanical constraints of the design.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common features such as low power consumption and glitch immunity but differ in reset thresholds and output configurations. The ADM6320 variant specifically offers multiple threshold options within the 2.5 V to 5 V range.
