ADM811ZART-REEL

Supervisors Overview

The ADM811ZART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., housed in an SOT-143-4 surface-mount package. It features a threshold voltage of 2.32 V and provides an active low reset output with manual reset capability. The device monitors a single input, operates within a maximum supply voltage of 5.5 V, and includes a reset delay time of 560 ms. It functions across a temperature range of -40°C to +85°C, consumes 15 µA of operating current, and has an overvoltage threshold of 2.35 V.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems with a dedicated manual reset function.
• Delivers an active low reset signal upon detection of undervoltage conditions below the specified threshold.
• Designed for low-power applications with minimal operating current consumption during normal operation.

Supervisors Applications

• Microprocessor system power monitoring
• Controller board voltage supervision
• Intelligent instrument power management

Supervisors Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to limited availability status. Confirm that the specific suffix matches the required 2.32 V threshold variant. Check RoHS compliance documentation as indicated in official specifications. Ensure storage conditions maintain integrity prior to assembly. Validate pinout compatibility with target PCB footprint before integration.

Supervisors Selection Notes

Select this variant when a 2.32 V threshold is required for low-voltage rail monitoring. The active low output suits logic families requiring a low signal for reset assertion. Consider the 560 ms delay for stable power-up sequences. The SOT-143-4 package offers space efficiency for compact designs. Verify thermal requirements against the specified operating temperature range.
