ADM1818-R23AKSZ-RL

Supervisors Overview

The ADM1818-R23AKSZ-RL is a single-channel voltage supervisor IC manufactured by Analog Devices Inc. It provides simple reset and power-on reset functions with an open-drain or open-collector output that asserts low. The device monitors a single input voltage against a fixed threshold of 2.31V. It features a minimum reset timeout of 100ms to ensure stable system initialization. Designed for surface-mount installation, it operates within a temperature range of -40°C to +105°C TA and is housed in a compact SC-70-3 package.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output
• Monitors single supply voltage against fixed threshold
• Ensures stable startup with defined reset timeout

Supervisors Applications

• Embedded systems requiring power supervision
• Microcontroller reset circuits
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'R23' confirms the 2.31V threshold requirement for your design. Confirm the 'S' indicates the SC-70-3 package variant compatible with your PCB footprint. Check current manufacturing status as this part may be discontinued or subject to limited availability compared to newer revisions.

Supervisors Selection Notes

Select this component when a fixed 2.31V monitoring threshold is required for low-voltage systems. Ensure the open-drain output configuration matches your microcontroller's reset pin requirements. Verify that the SC-70-3 package size fits within your board space constraints and thermal management needs.

Supervisors Part Context

This component belongs to the ADM1818 series of voltage supervisors from Analog Devices. It is functionally related to other parts in the ADM1810-13 and ADM1815-18 series documentation. The part serves as a dedicated supervisory circuit for maintaining system integrity during power fluctuations.
