ADM1232ARNZ-REEL7

Supervisors Overview

The ADM1232ARNZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 4.5 V to 5.5 V and features selectable threshold voltages at 4.37 V and 4.62 V. The device provides an active low, open drain output with a manual reset capability and includes an integrated watchdog timer. It supports a reset delay time of 1 second and consumes 500 uA of operating current. Power failure detection is enabled, and the unit is housed in an SOIC-8 package suitable for surface mount applications across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Features power failure detection capability

Supervisors Procurement Notes

Verify that the specific suffix REEL7 matches the required tape-and-reel packaging configuration for automated assembly processes. Confirm that the SOIC-8 package variant aligns with the designated footprint on the target printed circuit board. Ensure the selected threshold voltage settings meet the precise requirements of the monitored power rail. Check for any regional distribution restrictions or lead time constraints associated with this specific reel quantity before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a supervisory circuit with integrated watchdog functionality and power failure detection is required. The open-drain output type necessitates consideration of external pull-up resistor values in the design. Verify that the 500 uA operating current fits within the system's power budget constraints. Ensure the 1-second reset delay time is compatible with the startup sequence requirements of the controlled logic devices.

Supervisors Part Context

This part belongs to the ADM1232A series of microprocessor supervisors from Analog Devices. It shares functional similarities with other members of the family but differs in package style and specific electrical characteristics such as operating current and output drive type. The REEL7 designation indicates a specific manufacturing lot and packaging format distinct from tube or cut-tape variants.
