ADM1232AARNZ-REEL

Supervisors Overview

The ADM1232AARNZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor and microcontroller reset generation. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 500 uA and power dissipation of 900 uW. The device features selectable threshold voltages of 4.37 V and 4.62 V for monitoring a single input. It provides an active low, open drain output and includes a manual reset function alongside a watchdog timer. The reset delay time is specified at 1 second. Packaged in SOIC-8 format on a reel, it supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality via dedicated pin
• Features selectable voltage thresholds for flexible supervision
• Provides active low open drain reset output

Supervisors Applications

• Microprocessor reset generation
• Microcontroller supervision
• Voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix REEL indicates reel packaging when sourcing. Confirm the exact threshold voltage selection (4.37 V or 4.62 V) required for the application design. Ensure compatibility with the SOIC-8 footprint and check lead-free status against project requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision with integrated watchdog capabilities. Consider the 1-second reset delay and open drain output characteristics when designing the reset network. Evaluate the 500 uA operating current against power budget constraints. Verify that the 4.5 V to 5.5 V operating range aligns with the system's power supply rails.

Supervisors Part Context

This part belongs to the ADM1232A series of microprocessor supervisors from Analog Devices. It is distinct from standard ADM1232 variants by its specific A-grade specifications and reel packaging configuration. The device complements other PMIC offerings by providing essential reset and watchdog functions in a compact SOIC-8 package suitable for space-constrained designs.

Supervisors Replacement Considerations

ADM1232AARNZ is a direct tube-packaged alternative offering identical electrical performance without the reel configuration.
