ADM1232ARWZ-REEL7

Supervisors Overview

The ADM1232ARWZ-REEL7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in microprocessor and microcontroller systems. It features a single monitored input with adjustable or selectable voltage thresholds, specifically documented at 4.37 V and 4.62 V. The device provides a push-pull output driver and includes manual reset functionality alongside a watchdog timer. It operates within a supply voltage range of up to 5.5 V and supports a reset delay time of 1 second. The component is housed in a 16-pin SOIC package and is rated for an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Supports manual reset input for user-initiated control
• Features adjustable or selectable voltage threshold detection
• Provides push-pull output drive capability

Supervisors Applications

• Microprocessor supervision
• Microcontroller system monitoring
• Voltage supervisor circuits

Supervisors Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact 16-pin SOIC configuration. Check RoHS compliance status as indicated in official documentation. Validate that the manual reset and watchdog features are required for the design.

Supervisors Selection Notes

Select this component when a supervisory circuit with integrated watchdog and manual reset capabilities is required. The adjustable threshold feature allows flexibility in setting trip points. The push-pull output simplifies interface logic compared to open-drain alternatives. Ensure the 16-pin SOIC package fits the board layout constraints.

Supervisors Part Context

This part belongs to the ADM1232 family of microprocessor supervisors. The base model ADM1232 offers similar core functionalities. Variations in the suffix typically indicate packaging differences, such as tube versus reel. The ADM1232 series is designed for reliable power management in embedded systems requiring voltage oversight.

Supervisors Replacement Considerations

ADM1232ARMZ is listed as a direct replacement for the discontinued ADM1232ARM variant.
