ADM823MYKS-R7

Supervisors Overview

The ADM823MYKS-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. It features a manual reset capability and a watchdog timer for enhanced system reliability. The device operates within a supply voltage range of 1.63 V to 5.5 V, with a specific threshold voltage of 2.32 V. It draws a typical operating current of 40 µA and offers a reset delay time of 280 ms. The component is housed in a 5-lead SC-70 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors power supply voltage levels and ensures code execution integrity
• Integrates a watchdog timer and manual reset functionality
• Provides high accuracy voltage supervision with low power consumption

Supervisors Applications

• Microprocessor-based system power monitoring
• Code execution integrity verification
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the exact threshold voltage specification (2.32 V) against the official datasheet revision prior to procurement. Confirm the package type is 5-lead SC-70 and ensure compatibility with the target board's footprint. Check for RoHS compliance status as indicated in the manufacturer documentation. Validate that the manual reset and watchdog features align with the system design requirements.

Supervisors Selection Notes

Select this component when a low-power, single-channel supervisor with integrated watchdog and manual reset is required. It is suitable for applications needing precise voltage monitoring at 2.32 V threshold. Consider the 5-lead SC-70 package size for space-constrained designs. Ensure the operating temperature range meets the environmental conditions of the application.

Supervisors Part Context

The ADM823 series includes variants like ADM823, ADM824, and ADM825, which differ primarily in their reset threshold voltages. The MYKS suffix indicates a specific threshold and packaging configuration within this family. These devices are part of Analog Devices' PMIC - Supervisors line, focusing on reliable system management in embedded environments.

Supervisors Replacement Considerations

Direct substitutes include other ADM823 variants with matching threshold voltages, such as ADM823MYKSZ-R7. Verify pinout compatibility and electrical specifications before substitution. Alternative supervisors from other manufacturers may require circuit redesign due to differences in reset timing or threshold accuracy.
