ADM824SYKSZ-REEL7

Supervisors Overview

The ADM824SYKSZ-REEL7 is a high/low watchdog supervisor integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.65V to 5.5V and features a fixed reset threshold voltage of 3.08V with an accuracy of 1.5%. The device includes a built-in watchdog timer with a timeout period of 200ms and provides a push-pull active-high or active-low output. It is housed in a compact SC-70-5 package, suitable for surface-mount applications across an operating temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system monitoring
• Provides dual high/low voltage supervision capabilities
• Features configurable active-high or active-low reset output

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the specific suffix 'SY' against official Analog Devices documentation to confirm the exact reset threshold voltage and output polarity configuration. Ensure the SC-70-5 package dimensions align with your PCB footprint requirements. Confirm that the 200ms watchdog timeout meets your system's timing constraints. Validate that the 1.5% threshold accuracy is sufficient for your application's noise margins.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer is required in a minimal footprint. Consider the 1.65V minimum operating voltage for low-power battery applications. Evaluate the need for both high and low voltage detection versus single-threshold supervisors. Compare the SC-70-5 package size against available alternatives if board space is constrained.

Supervisors Part Context

This part belongs to the ADM824 series of supervisory circuits from Analog Devices. It is designed for applications requiring reliable system reset management under varying power conditions. The series typically offers various threshold options and packaging configurations to suit different design needs.

Supervisors Replacement Considerations

Consult Analog Devices official cross-reference guides for verified substitutes. Verify pin compatibility and electrical parameter equivalence before substitution.
