ADM825YYKS-R7

Supervisors Overview

The ADM825YYKS-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It features a manual reset function and is housed in a compact SC-70-5 package. The device operates within a supply voltage range of 1.6 V to 5.5 V, with a typical threshold voltage of 3.08 V for the monitored input. It includes a reset delay time of approximately 280 ms and maintains an accuracy of 2.5%. The component supports push-pull output configuration and functions reliably across an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset capability for enhanced system reliability
• Provides precise voltage supervision with high accuracy thresholds
• Features a compact surface-mount package suitable for space-constrained designs

Supervisors Applications

• Portable electronics requiring low-power supervision
• Industrial control systems needing reliable reset mechanisms
• Embedded systems with strict voltage monitoring requirements

Supervisors Procurement Notes

Verify the specific suffix YYKS against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with your board's thermal and voltage constraints. Confirm availability through authorized distributors as supply status may vary. Cross-reference the datasheet revision date to ensure access to the latest technical specifications and handling guidelines.

Supervisors Selection Notes

Select this component when a combined watchdog and manual reset function is required in a minimal footprint. Consider the 2.5% accuracy and 280 ms delay for timing-sensitive applications. Evaluate the SC-70-5 package size against PCB real estate limitations. Verify that the 1.6 V to 5.5 V operating range aligns with your system's power rails and noise margins.

Supervisors Part Context

This part belongs to the ADM825 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and packages, including SOT-23 and SC-70 options. The ADM825YYKS-R7 specifically denotes the SC-70-5 package variant with a 3.08 V threshold. This family is designed for cost-effective and reliable power management in consumer and industrial devices.

Supervisors Replacement Considerations

Check for ADM825TYKSZ-R7 or ADM825SYKSZ-R7 if different threshold voltages are needed. These variants share similar functionality but offer distinct reset thresholds. Verify package compatibility and electrical parameters before substitution.
