ADM1818-10AKS-REEL

Supervisors Overview

The ADM1818-10AKS-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed threshold voltage of 4.49 V for overvoltage detection. The device provides a push-pull output with a reset delay time of 250 ms. It supports manual reset functionality and lacks a watchdog timer or battery backup switch. The component is available in an SC-70-3 surface-mount package and functions as a voltage supervisory IC.

Supervisors Feature Summary

• Provides hardware-based system reset generation upon power-up or brown-out events
• Includes manual reset input capability for external control
• Features overvoltage detection to protect against excessive supply levels

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded controllers
• Overvoltage protection circuits

Supervisors Procurement Notes

Verify the specific suffix and reel configuration when ordering, as packaging variations may exist. Confirm availability status directly with authorized distributors, as this part may be subject to limited supply conditions. Ensure the SC-70-3 package type matches your PCB footprint requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 4.49 V threshold is required for system supervision. It is suitable for designs needing manual reset intervention and push-pull outputs. Consider alternative packages if space constraints differ from the SC-70-3 form factor. Verify that the 250 ms reset delay aligns with your system's startup timing requirements.
