ADM1811-5AKS-RL7

Supervisors Overview

The ADM1811-5AKS-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.1 V to 5.5 V and features a fixed reset threshold of 4.62 V typical. The device provides a reset output with a delay time of 250 ms. It is available in an SC-70 (SOT-323) surface-mount package and supports operation across a temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Provides robust power-system supervision for electronic systems requiring reset upon voltage deviation
• Utilizes a factory-set reset threshold to monitor input voltages without external components
• Delivers a reliable reset signal with a defined delay time to ensure stable system startup

Supervisors Applications

• Safety-critical automotive applications
• Microprocessor reset circuits
• Voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Check current availability status as distribution may vary. Ensure the package type matches SC-70/SOT-323 requirements for your PCB design.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for 5 V systems. Consider the 250 ms reset delay for timing constraints. Verify compatibility with the SC-70 footprint. Compare against other ADM181x variants if different thresholds or packages are needed.

Supervisors Part Context

This part belongs to the ADM181x series of voltage monitoring circuits designed for applications where an electronic system needs to be reset when voltage increases above or below a set point. It is a simple supervisor suitable for microprocessor reset functions.

Supervisors Replacement Considerations

ADM1811-5ARTZ-REEL is a parameter-equivalent alternative from the same manufacturer.
