ADM823TYKS-R7

Supervisors Overview

The ADM823TYKSZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for active low watchdog supervision. It operates within a supply voltage range of up to 5.5 V and features a reset threshold voltage of 3.08 V with an accuracy of 2.5%. The device includes a manual reset input, a push-pull output type, and a watchdog timer function. It exhibits a reset delay time of 280 ms and consumes a typical operating supply current of 24 uA. The component supports overvoltage detection at 3.11 V and lacks power failure detection or battery backup switching capabilities. It is housed in an SC-70-5 package and functions reliably across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates active low watchdog supervision with manual reset capability for system monitoring
• Provides precise voltage supervision with factory-set threshold and high accuracy
• Features push-pull output configuration for robust signal driving
• Operates efficiently with low quiescent current consumption

Supervisors Applications

• Microcontroller system supervision
• Embedded system reset management
• Watchdog timer implementation in industrial controls
• Voltage monitoring in portable electronics

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation, as variations such as Z or R7 may indicate specific packaging or compliance attributes that do not alter the core electrical function. Confirm availability status through authorized distributors, as supply constraints may exist. Ensure the SC-70-5 package matches your PCB footprint requirements. Cross-reference the threshold voltage specifications with your system design needs to ensure compatibility with the 3.08 V reset level. Check for any regional shipping restrictions or lead time limitations before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a dedicated watchdog supervisor with manual reset is required for systems operating at 3.08 V thresholds. Consider its low current consumption suitable for battery-powered applications. Evaluate the SC-70-5 package size against board space constraints. Verify that the 280 ms reset delay aligns with your system's startup timing requirements. Assess the need for overvoltage protection features provided by the 3.11 V threshold. Compare performance against other supervisory ICs if higher accuracy or different voltage levels are necessary.
