ADM1818-R23AKSZ-R7

Supervisors Overview

The ADM1818-R23AKSZ-R7 is a single-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc. It features an open-drain or open-collector output with a low-active reset signal. The device monitors a supply voltage against a fixed threshold of 2.31V, triggering a reset when the voltage falls below this level. It includes a minimum reset timeout of 100ms to ensure stable power-up conditions. The component operates within a temperature range of -40°C to 105°C and is housed in a surface-mount SC-70 (SOT-323) package.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for microprocessor systems
• Features an open-drain or open-collector output compatible with various logic families
• Ensures system stability with a guaranteed minimum reset timeout period

Supervisors Applications

• Microcontroller power supply monitoring
• Embedded system reset circuits
• Battery-powered device supervision

Supervisors Procurement Notes

Verify that the suffix 'R7' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the specific 2.31V threshold aligns with the target application's voltage requirements. Ensure compatibility with the SC-70-3 footprint on the printed circuit board layout. Check for any specific handling instructions related to the surface-mount technology package.

Supervisors Selection Notes

Select this component when a fixed 2.31V threshold is appropriate for the monitored rail. The open-drain output allows for flexible interfacing with different logic levels through external pull-up resistors. Consider the operating temperature range to ensure reliability in the intended environment. This part is suitable for applications requiring a simple, low-component-count reset solution without manual reset inputs.

Supervisors Part Context

This part belongs to the ADM1818 series of voltage supervisors from Analog Devices. The series offers various threshold voltages to accommodate different supply rails. The R7 suffix indicates the standard reel packaging option for high-volume manufacturing. The device is designed for general-purpose reset applications in consumer and industrial electronics.

Supervisors Replacement Considerations

The ADM1818-R23AKS-RL7 is a parameter-equivalent substitute. Verify pinout and electrical specifications match before substitution.
