ADM1817-R22AKS-RL

Supervisors Overview

The ADM1817-R22AKS-RL is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input channel with a threshold voltage of 2.18 V. The device features a push-pull output type and provides manual reset capability. It operates within a supply voltage range up to 5.5 V and includes a reset delay time of 250 ms. The component supports surface mount installation in an SC-70-3 package. It functions reliably across a temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable low-cost voltage monitoring for standard power supply voltages
• Features a push-pull output configuration for direct interface compatibility
• Includes manual reset functionality for system control flexibility

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply rails
• Microprocessor reset circuits requiring precise threshold detection
• Embedded systems needing voltage supervision in compact packages

Supervisors Procurement Notes

Verify the exact suffix RL against current manufacturer documentation to confirm reel packaging specifications. Confirm RoHS compliance status as historical data may vary. Ensure the SC-70-3 package dimensions match your PCB footprint requirements. Check for any updated datasheet revisions that might affect electrical characteristics or pin definitions before finalizing procurement.

Supervisors Selection Notes

Select this component when a specific 2.18 V threshold is required for voltage supervision. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the SC-70-3 package size for space-constrained designs. Verify that the 250 ms reset delay meets the timing requirements of the monitored microprocessor or logic circuit.

Supervisors Part Context

This part belongs to the ADM1817 series of voltage supervisors from Analog Devices. These devices are designed for cost-sensitive applications requiring simple reset generation. The series typically offers multiple threshold options to accommodate various standard voltage levels. The ADM1817 variant specifically targets applications needing a 2.18 V trip point with robust performance in industrial environments.
