ADM1811-5ART-REEL

Supervisors Overview

The ADM1811-5ART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator integrated circuit. It operates within a supply voltage range up to a maximum of 5.5 V and features a fixed threshold voltage of 5 V for monitoring power rails. The device utilizes an SMD/SMT installation style in a compact SOT-23-3 package. It provides a push-pull output type and includes a reset delay time of 250 ms to ensure stable system initialization. The component monitors a single input without manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Provides reliable power-on reset generation with a fixed 5 V threshold for precise voltage supervision
• Features a push-pull output stage capable of driving digital logic interfaces directly
• Ensures system stability through a defined 250 ms reset delay period during power transitions

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered equipment voltage supervision
• Portable electronic device power management systems

Supervisors Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as -REEL or -RL7 indicate specific tape and reel packaging formats that may affect handling but not electrical function. Confirm availability status through authorized distributors, as supply constraints may apply to this specific part number variant. Ensure compatibility with existing PCB footprint designs utilizing the SOT-23-3 package dimensions.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for system supervision without the need for adjustable voltage references. The push-pull output offers stronger drive capability compared to open-drain alternatives, suitable for direct interfacing with digital inputs. Consider the 250 ms delay duration to ensure it aligns with the startup requirements of the target processor or memory devices in the design.

Supervisors Part Context

This part belongs to the ADM1811 series of voltage supervisors from Analog Devices, which are designed for simple, low-cost power monitoring applications. The series typically offers various threshold voltages and output configurations to suit different system architectures. The -ART designation indicates the specific temperature grade and packaging format used for surface-mount assembly in consumer and industrial electronics.
