ADM6320BX45ARJZ-R7

Supervisors Overview

The ADM6320BX45ARJZ-R7 is a supervisory circuit from Analog Devices, designed for monitoring microprocessor-based systems. It features a fixed reset threshold voltage of 4.5V and an open-drain active-low output stage. The device includes a manual reset input and a watchdog timer function. It operates within a supply voltage range up to 5.5V and maintains functionality down to VCC = 1V. The component is housed in a 5-lead SOT-23 package and supports surface mount installation.

Supervisors Feature Summary

• Integrates power supply supervision with a dedicated watchdog timer for system reliability
• Provides manual reset capability via a dedicated input pin
• Features an open-drain active-low reset output stage
• Ensures valid reset output states even at low supply voltages

Supervisors Applications

• Microprocessor systems requiring voltage supervision
• Controllers needing watchdog timer protection
• Intelligent instruments with power management requirements

Supervisors Procurement Notes

Verify the specific suffix 'RJZ' indicates RoHS compliance and tape-and-reel packaging configuration. Confirm the 'BX' code corresponds to the 4.5V threshold variant against the official datasheet. Ensure the ordering part number matches the exact package and environmental specifications required for the design.

Supervisors Selection Notes

Select this component when a fixed 4.5V threshold is required for the monitored rail. The open-drain output allows flexibility in interfacing with various logic levels. Consider the industrial temperature range and low quiescent current if power efficiency is critical for the application environment.

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 watchdog timers and manual reset inputs but differ in reset threshold voltages and output stages. The ADM6320 specifically offers an open-drain output option.

Supervisors Replacement Considerations

Other parts in the ADM6320 series with different threshold codes (e.g., BX43, BX46) may be compatible if the voltage level permits. Verify that the replacement maintains the same open-drain output type and package footprint.
