ADM823YYKS-R7

Supervisors Overview

The ADM823YYKS-R7 is a supervisory circuit from Analog Devices that monitors power supply voltage levels and code execution integrity. It operates with an ultra-low quiescent current of approximately 6 µA under nominal conditions when monitoring a single power rail, making it suitable for battery-powered applications. The device features precision monitoring within the 2.5 V to 5 V range and offers seven reset threshold options spanning from 2.19 V to 4.63 V. It includes a manual reset input and provides a minimum reset timeout of 140 ms. The component is housed in a compact 5-TSSOP (SC-70-5) package with a push-pull output configuration.

Supervisors Feature Summary

• Monitors power supply voltage levels and ensures code execution integrity
• Ultra-low quiescent current consumption for energy efficiency
• Provides multiple selectable reset threshold voltages for flexibility
• Includes manual reset input capability for system control

Supervisors Applications

• Battery-powered electronic systems requiring low standby current
• Microcontroller-based designs needing reliable power supervision
• Portable devices where space and power efficiency are critical

Supervisors Procurement Notes

Verify the specific suffix YYKS against the manufacturer's official documentation to confirm pinout, threshold voltage, and package type compatibility. Ensure the ordering part number matches the required reset threshold option, as variations exist within the ADM823 family. Cross-reference the datasheet revision to confirm electrical characteristics and mechanical dimensions before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a precise power supervisor with low quiescent current is required for single-rail monitoring. Consider the available reset threshold options to match the target supply voltage. Evaluate the 5-TSSOP package size constraints against board layout requirements. Confirm that the manual reset input functionality aligns with the system's reset strategy and timing requirements.

Supervisors Part Context

The ADM823YYKS-R7 belongs to the ADM823/ADM824/ADM825 series of supervisory circuits designed by Analog Devices. These components are engineered to monitor voltage levels and ensure system reliability by resetting microcontrollers or logic circuits during brown-out or over-voltage events. The series is widely used in industrial, consumer, and communication equipment where stable power management is essential.

Supervisors Replacement Considerations

Direct substitutes include other ADM823 variants with compatible thresholds and packages. Verify pin-to-pin compatibility and electrical specifications such as quiescent current and reset timeout before substitution. Consult the manufacturer's cross-reference guide for approved alternatives.
