ADM811RARTZ-REEL7

Supervisors Overview

The ADM811RARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator IC. 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 utilizes a SOT-143-4 surface-mount package. Key electrical parameters include a threshold voltage of 2.63 V, an overvoltage threshold of 2.68 V, and a reset delay time of 240 ms. It maintains an accuracy of 1.5% and draws a working supply current of 15 uA. The component supports power dissipation of 200 mW and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides manual reset functionality for precise system control
• Features active low output for direct interface compatibility
• Delivers high accuracy voltage supervision with minimal quiescent current

Supervisors Applications

• Microprocessor reset generation in embedded systems
• Voltage monitoring for battery-powered devices
• Power supply supervision in industrial control units

Supervisors Procurement Notes

Verify the specific suffix RARTZ against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as availability may be restricted. Ensure the ordering information matches the required reel packaging specifications for automated assembly processes.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-channel voltage supervision. The active low output and manual reset feature suit applications needing explicit user intervention for system recovery. Consider the SOT-143-4 package size for space-constrained designs requiring surface mount technology.

Supervisors Part Context

This part belongs to the ADM811 series of microprocessor supervisors from Analog Devices. The series offers various threshold voltages and output configurations to accommodate different logic families and power rails. The REEL7 designation indicates tape and reel packaging suitable for high-volume manufacturing environments.

Supervisors Replacement Considerations

Check for ADM811 variants with identical 2.63 V thresholds and active low outputs. Verify pinout compatibility with the SOT-143-4 package before substitution.
