ADM1232ANZ

Supervisors Overview

The ADM1232ANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in an 8-pin DIP package. It monitors supply voltage with selectable thresholds of 4.5 V or 4.75 V and includes a watchdog timer with adjustable reset delays of 150 ms, 600 ms, or 1.2 s. The device operates within a supply range of 4.5 V to 5.5 V and supports temperatures from -40°C to +85°C. It features open-drain outputs and detects strobe pulse widths as narrow as 20 ns.

Supervisors Feature Summary

• Detects microprocessor lock-ups via adjustable watchdog timer
• Monitors supply voltage with selectable precision thresholds
• Supports fast strobe pulse width detection for high-speed processors

Supervisors Applications

• Microprocessor system supervision
• Embedded controller reset generation
• Industrial automation control units

Supervisors Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold and delay settings. Confirm package type compatibility during integration. Check current availability status as older revisions may be discontinued. Ensure RoHS compliance documentation matches project requirements.

Supervisors Selection Notes

Select this component when precise voltage monitoring and watchdog functionality are required for microprocessor systems. Consider the available threshold options and reset delay configurations to match system timing requirements. Verify package suitability for the intended PCB layout and thermal conditions.

Supervisors Part Context

This part belongs to the ADM1232 family of microprocessor supervisors. It serves as a pin-compatible upgrade for legacy MAX1232 and Dallas DS1232 devices. The series provides essential reset generation and system monitoring capabilities for embedded applications requiring reliable power management.

Supervisors Replacement Considerations

ADM1232ARMZ is a direct surface-mount replacement. ADM1232AARM is another variant within the same functional family.
