ADM1816-R23ART-RL7

Supervisors Overview

The ADM1816-R23ART-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It features a fixed threshold voltage of 2.31V, ensuring precise detection of under-voltage conditions. The device provides a push-pull output capable of driving logic interfaces directly. It supports manual reset functionality via an external input pin, allowing for controlled system recovery. The component operates within a supply voltage range up to 5.5V and maintains accuracy across an industrial temperature range of -40°C to +85°C. Packaged in the compact SOT-143-4 surface-mount format, it integrates low quiescent current consumption suitable for battery-powered applications.

Supervisors Feature Summary

• Provides reliable power monitoring with a fixed 2.31V threshold for consistent under-voltage detection.
• Features a push-pull output stage that eliminates the need for external pull-up resistors.
• Includes a manual reset input pin to allow user-initiated system recovery or watchdog bypass.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Microcontroller-based systems needing stable power supervision
• Battery-operated equipment with low standby current requirements

Supervisors Procurement Notes

Verify the specific suffix 'R23' confirms the 2.31V threshold requirement for your design. Confirm the 'ART' package designation matches the SOT-143-4 footprint constraints. Ensure the 'RL7' reel specification aligns with your automated assembly equipment capabilities. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.31V threshold is required for precise power monitoring. The push-pull output simplifies PCB layout by removing external pull-up components. Consider the manual reset feature if system control requires explicit recovery triggers. Verify that the SOT-143-4 package dimensions fit within the available board space constraints for the target application.

Supervisors Part Context

This part belongs to the ADM1816 series of voltage supervisors from Analog Devices. It is engineered for simple, cost-effective power management solutions. The series typically offers various threshold options to accommodate different rail voltages. It serves as a fundamental building block for ensuring system reliability in embedded electronics.

Supervisors Replacement Considerations

Check for direct equivalents within the ADM1816 family with matching thresholds. Verify pin compatibility if substituting with other SOT-143-4 supervisors. Ensure replacement parts support the same manual reset functionality and output drive characteristics.
