ADM1232ARMZ-REEL7

Supervisors Overview

The ADM1232ARMZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 4.5 V to 5.5 V and features selectable threshold voltages, specifically 4.37 V and 4.62 V for under-voltage detection, with over-voltage thresholds at 4.49 V and 4.74 V. The device provides a push-pull output type and includes a manual reset function alongside a watchdog timer. It exhibits a typical quiescent current of 50 uA and supports a reset delay time of 1 second. The component is housed in an MSOP-8 package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality for user-initiated control
• Features selectable voltage thresholds for flexible supervision
• Provides push-pull output configuration

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Embedded systems requiring watchdog timer protection
• Portable devices needing low-power voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected threshold voltage options match the target application requirements. Check for regional distribution restrictions as availability may vary by location. Validate that the MSOP-8 package dimensions fit the intended PCB layout constraints.

Supervisors Selection Notes

Choose this component when a single-channel supervisor with integrated watchdog capabilities is required. The selectable thresholds allow adaptation to various standard voltage rails without external resistors. Consider the 50 uA operating current for battery-sensitive designs. The push-pull output simplifies interface logic compared to open-drain alternatives. Verify thermal performance within the specified -40°C to +85°C operational range.

Supervisors Part Context

This part belongs to the ADM1232 series of microprocessor supervisors from Analog Devices. It serves as a successor or variant to earlier versions like the ADM1232ARM, offering updated packaging and manufacturing standards. The series focuses on providing reliable reset generation and system monitoring for digital circuits. It complements other PMIC solutions by handling critical voltage supervision tasks independently.

Supervisors Replacement Considerations

ADM1232ARMZ is a direct substitute available in tube packaging.
