ADM1232ARMZ-REEL

Supervisors Overview

The ADM1232ARMZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single input voltages. It operates within a supply voltage range up to 5.5 V and features selectable threshold voltages of 4.37 V and 4.62 V, with overvoltage thresholds at 4.49 V and 4.74 V. The device includes a manual reset function, a watchdog timer, and a push-pull output type. It has a reset delay time of 1 second and consumes 50 uA of operating current. The component is housed in an MSOP-8 package and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality via dedicated pin
• Features selectable voltage thresholds for flexible configuration
• Provides push-pull output drive capability

Supervisors Applications

• Microprocessor reset generation
• Voltage supervision in embedded systems
• Power management monitoring circuits

Supervisors Procurement Notes

Verify availability status as the REEL variant may be subject to limited supply or factory special orders. Confirm package integrity upon receipt. Ensure compatibility with existing design specifications regarding threshold selection and thermal requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset is required. Consider the MSOP-8 footprint and operating temperature range. Verify that the selectable thresholds align with the target system voltage levels. Check for direct replacements if the reel packaging is unavailable.

Supervisors Part Context

The ADM1232 series belongs to Analog Devices' line of microprocessor supervisors. These devices are engineered to provide reliable reset signals and system monitoring. The ARMZ suffix indicates a lead-free RoHS-compliant version in the MSOP-8 package, distinguishing it from older non-compliant variants like the ADM1232ARM which is discontinued.

Supervisors Replacement Considerations

ADM1232ARMZ is a direct replacement for the discontinued ADM1232ARM.
