ADM1813-5ART-RL

Supervisors Overview

The ADM1813-5ART-RL is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 5 V for power monitoring. The device provides a reset delay time of 250 ms to ensure stable system initialization. It draws a typical operating supply current of 16 uA, supporting low-power applications. The component utilizes an SOT-23-3 surface-mount package and offers an open-drain output type. It functions as a single-input reset generator without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides automated power-on reset generation with a fixed 250 ms delay for reliable system startup
• Features ultra-low quiescent current consumption suitable for battery-powered designs
• Includes overvoltage detection capability to protect against supply rail anomalies

Supervisors Applications

• Microcontroller power supply supervision
• Embedded system reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix ART-RL corresponds to the SOT-23-3 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the 5 V threshold matches the target supply rail requirements. Check for any obsolescence notices or lifecycle changes directly from Analog Devices.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for single-supply monitoring. The SOT-23-3 package is ideal for space-constrained PCB layouts. Consider the 16 uA current draw for efficiency-critical designs. Verify that the open-drain output interface is compatible with the downstream logic levels. Ensure the 250 ms delay meets the minimum initialization time requirements of the controlled circuitry.
