ADM1232ARMZ

Supervisors Overview

The ADM1232ARMZ is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs in microprocessor and microcontroller systems. It operates within a supply voltage range of 4.5 V to 5.5 V and features an active high or open drain output configuration. The device includes a watchdog timer with a reset delay time of approximately 610 ms and supports manual reset functionality. It is housed in an 8-MSOP surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer with configurable timeout for system reliability
• Supports both active high and open drain output configurations
• Includes manual reset input capability for user-initiated recovery
• Operates on a single monitored voltage channel

Supervisors Applications

• Microprocessor supervision
• Microcontroller system monitoring
• Embedded system power management

Supervisors Procurement Notes

Verify the specific suffix (e.g., REEL7 vs standard tube) against your assembly requirements, as packaging formats differ between reel and tube options. Confirm that the selected variant matches the required threshold voltages and reset timing specifications for your design. Ensure compatibility with the 8-MSOP footprint during PCB layout review.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. Consider the available threshold options and reset delay characteristics to match system stability needs. Verify that the 8-MSOP package size fits the board constraints and that the operating temperature range meets environmental conditions.

Supervisors Part Context

This part belongs to the ADM1232 series of microprocessor supervisors from Analog Devices. It serves as a direct replacement for the discontinued ADM1232ARM variant. The series focuses on providing essential reset generation and watchdog capabilities in a compact surface-mount package for embedded applications.

Supervisors Replacement Considerations

The ADM1232ARM is listed as a direct substitute for the ADM1232ARMZ, although the former is marked as obsolete. Verify pinout and electrical parameter equivalence before transitioning.
