ADM1232ARWZ

Supervisors Overview

The ADM1232ARWZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in microprocessor and microcontroller systems. It operates within a supply voltage range of 4.5 V to 5.5 V and features selectable threshold voltages of 4.5 V and 4.75 V. The device provides a reset delay time of 610 ms and includes an integrated watchdog timer. It is housed in a 16-lead SOIC package with surface mount installation. The output configuration supports active high and open drain modes, while the component functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Supports selectable voltage threshold levels
• Provides active high and open drain output configurations

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix ARWZ against official Analog Devices documentation to confirm the exact package type and tape/reel or tube packaging details. Ensure compatibility with the target PCB footprint for the SOIC-16 package. Cross-reference the datasheet for any recent manufacturing site changes or RoHS compliance updates prior to final procurement authorization.

Supervisors Selection Notes

Select this component when a single-channel supervisor with configurable thresholds and watchdog functionality is required. Verify that the 610 ms reset delay aligns with the system startup timing requirements. Confirm that the operating voltage range covers the specific rail being monitored and that the output drive capability matches the downstream logic inputs.

Supervisors Part Context

This part belongs to the ADM1232 series of microprocessor supervisors from Analog Devices. The series focuses on providing reliable reset signals and system protection through integrated watchdog features. The ARWZ designation typically indicates a specific package variant within this family, distinguishing it from other pin counts or thermal packages offered in the broader product line.

Supervisors Replacement Considerations

Direct replacement options include the ADM1232ARMZ, which offers similar supervisory functions but utilizes an 8-MSOP package. Designers must evaluate pinout compatibility and physical footprint differences before substituting the 16-lead SOIC version with the 8-lead MSOP variant.
