ADM1818-20AKSZ-RL

Supervisors Overview

The ADM1818-20AKSZ-RL is a single-channel voltage supervisor IC from Analog Devices, designed for reliable power monitoring in electronic systems. It operates within an ambient temperature range of -40°C to +105°C and utilizes a surface-mount SC70-3 package with dimensions of 2.00 x 1.25mm. The device features a push-pull output type and provides a low-active reset signal. It monitors one input voltage channel, ensuring stable system operation by detecting under-voltage conditions.

Supervisors Feature Summary

• Provides reliable voltage supervision with a dedicated reset output for system protection
• Suitable for monitoring standard power supply voltages including 2.5 V, 3 V, 3.3 V, and 5 V rails
• Offers a compact SC70-3 surface mount package for space-constrained designs

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply voltages
• Microprocessor reset circuits requiring simple power-on reset functionality
• Portable electronics and battery-powered devices needing efficient power management

Supervisors Procurement Notes

Verify the specific threshold voltage variant matches the application requirement, as the ADM1818 series includes multiple options such as 2.31 V, 2.55 V, and others. Confirm the package type is SC70-3 and the output configuration aligns with the design. Ensure the operating temperature range covers the intended environmental conditions. Cross-reference the full part number to avoid confusion with similar suffixes or discontinued variants.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisor is needed for standard voltage rails. The push-pull output allows direct interfacing with digital logic without additional pull-up components. Consider the thermal performance and package size constraints. Verify that the reset timeout characteristics meet the system's startup requirements. Compare against other ADM181x variants if different threshold levels are required.

Supervisors Part Context

The ADM1818 series consists of reliable, low-cost voltage monitors with reset outputs. These devices are engineered for applications requiring precise supervision of power supplies. The family supports various threshold levels to accommodate different voltage standards. They are commonly used in consumer electronics, industrial controls, and communication equipment where power integrity is critical.
