ADM811ZARTZ-REEL7

Supervisors Overview

The ADM811ZARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor reset generation. It operates within a supply voltage range up to 5.5 V and features an active low output type with manual reset capability. The device monitors a single input channel and provides a precise threshold voltage of 2.32 V, with an overvoltage threshold of 2.35 V. It incorporates a fixed reset delay time of 560 ms and maintains an accuracy of 1.5%. The component functions in temperatures from -40 C to +85 C, consumes 15 uA of operating current, and dissipates 200 mW of power. It is housed in an SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Provides reliable microprocessor reset signals through voltage supervision with manual reset functionality.
• Delivers high precision monitoring with 1.5% accuracy and defined overvoltage detection thresholds.
• Optimized for low-power applications with minimal operating current consumption.

Supervisors Applications
