ADM1815-20ART-RL7

Supervisors Overview

The ADM1815-20ART-RL7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and generate reset signals. It operates within a supply voltage range of 2.5V to 5.5V, featuring a fixed threshold voltage of 2.0V for precise monitoring. The device utilizes an SOT-23-3 surface-mount package, ensuring compact integration into space-constrained designs. It provides a push-pull output configuration with a typical reset delay time of 200ms, facilitating reliable system initialization. The component supports operation across an industrial temperature range from -40°C to +85°C, making it suitable for diverse environmental conditions.

Supervisors Feature Summary

• Provides automated system reset generation upon detection of under-voltage conditions relative to the specified threshold.
• Features a push-pull output stage capable of sourcing and sinking current without requiring external pull-up resistors.
• Incorporates a fixed internal reset delay timer to ensure stable power supply settling before asserting the reset signal.

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Portable battery-operated equipment voltage monitoring
• Industrial control system reset generation

Supervisors Procurement Notes

Verify the specific suffix ARTZ or ART against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Confirm availability through authorized distributors as supply status may vary. Ensure the selected variant matches the required operating temperature range and package dimensions for your PCB layout.

Supervisors Selection Notes

Select this component when a fixed 2.0V threshold is appropriate for the monitored rail. Consider the push-pull output capability if driving loads directly without external components is required. Evaluate the SOT-23-3 footprint constraints against available board space. Compare against other ADM18xx variants if different thresholds or manual reset features are needed.

Supervisors Part Context

This part belongs to the ADM18xx series of supervisory circuits from Analog Devices, which offers various voltage thresholds and output configurations. The series is designed for cost-effective and reliable power management in embedded systems. The ADM1815 specifically targets applications requiring a fixed threshold with a simple, robust reset mechanism.

Supervisors FAQ

What is the reset delay time for the ADM1815-20ART-RL7?

The typical reset delay time is 200ms, allowing the power supply to stabilize before the reset signal is deasserted.

Does the ADM1815-20ART-RL7 support manual reset?

No, the ADM1815-20ART-RL7 does not include a manual reset input; it relies solely on automatic power-on reset and undervoltage detection.
