ADM1810-5ART-REEL

Supervisors Overview

The ADM1810-5ART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor single power supply rails. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 4.62 V for the monitored input. The device provides a push-pull, active-low reset output with a minimum reset timeout of 100 ms. Packaged in a surface-mount SOT-23-3 (SC-59) case, it supports an operating temperature range from -40°C to +125°C. This component serves as a reliable low-cost solution for ensuring system stability during power-up and brown-out conditions.

Supervisors Feature Summary

• Provides a dedicated reset signal triggered when the monitored voltage drops below the specified threshold level.
• Features a push-pull output stage capable of driving subsequent logic circuits directly without additional pull-up components.
• Ensures system integrity through a defined reset delay time that allows power supplies to stabilize before asserting the reset state.

Supervisors Applications

• Monitoring 5 V power supply rails in embedded systems
• Microprocessor reset generation in industrial control units
• Brown-out detection in battery-operated devices

Supervisors Procurement Notes

Verify the specific suffix ART against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm availability status with authorized distributors as supply constraints may apply. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the 4.62 V threshold with system voltage tolerances to prevent false triggering.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for 5 V system monitoring. The push-pull output simplifies interface design compared to open-drain variants. Consider the SOT-23-3 package size for space-constrained PCB layouts. Verify that the 100 ms minimum reset timeout aligns with the startup characteristics of the connected microprocessor or memory devices.

Supervisors Part Context

This part belongs to the ADM1810 series of voltage supervisors from Analog Devices. The series includes variants with different thresholds such as 2.5 V, 3 V, 3.3 V, and other 5 V options. The ADM1810-5ART specifically denotes the 4.62 V threshold version in the SOT-23-3 package. It is functionally similar to the ADM1811 but differs in output configuration and reset timing characteristics.

Supervisors Replacement Considerations

Direct substitutes include ADM1810-5ARTZ-REEL which shares identical electrical specifications and pinout. Other ADM1810 variants with different thresholds are not electrically compatible. Check for ADM810 series alternatives if push-pull output and similar package are required, though reset times may differ.
