ADM1811-10ARTZ-RL

Supervisors Overview

The ADM1811-10ARTZ-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It functions as a voltage monitor with an active low open-drain output featuring an internal pull-up resistor. The device monitors a single input voltage and provides reset signals when the supply deviates from specified thresholds. Typical trip points are 4.62 V and 4.35 V. It operates within a supply voltage range up to 5.5 V and includes a fixed reset delay time of 250 ms. The component is housed in a SOT-23-3 surface-mount package and supports an operating temperature range of -40°C to 105°C.

Supervisors Feature Summary

• Provides active low open-drain reset signal with internal pull-up resistor
• Monitors single voltage input for over-voltage or under-voltage conditions
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor reset circuits
• Voltage monitoring in electronic systems
• Battery-powered devices requiring supervision

Supervisors Procurement Notes

Verify exact availability through authorized distributors, as stock levels fluctuate. Confirm the specific suffix matches required trip points and packaging. Check RoHS compliance status for current production runs. Ensure the ordering part number aligns with the desired reel quantity and tape-and-reel specifications.

Supervisors Selection Notes

Select this component when a simple, low-pin-count supervisor is needed for single-rail monitoring. The open-drain output allows flexibility in interfacing with various logic families. Consider the 250 ms delay for system stability requirements. Verify that the typical trip voltages meet the specific threshold needs of the target application without external components.

Supervisors Part Context

This part belongs to the ADM181x family of voltage monitoring circuits designed for applications requiring system reset upon voltage anomalies. The series offers various threshold options and output configurations to suit different microprocessor and memory protection needs.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ADM181x series with matching trip points. Verify equivalent electrical characteristics such as reset delay and quiescent current before substitution.
