ADM1816-5AKS-REEL7

Supervisors Overview

The ADM1816-5AKS-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a precise threshold voltage of 3.06 V, designed for monitoring 3.3 V rails. The device provides brownout protection with a reset delay time of 250 ms. It utilizes an SC-70-3 surface-mount package and offers open drain or push-pull output configurations. The component lacks manual reset, watchdog timer, and battery backup switch functionalities.

Supervisors Feature Summary

• Provides precise voltage supervision for 3.3 V power rails
• Delivers automatic system reset upon undervoltage detection
• Supports flexible output drive configurations

Supervisors Applications

• Monitoring 3.3 V logic power supplies
• Brownout protection in embedded systems
• Microprocessor reset generation circuits

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical specifications. Confirm availability status as distribution channels may indicate limited stock or discontinuation. Ensure the SC-70-3 package variant matches the design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.06 V threshold is required for 3.3 V rail monitoring. Consider the 250 ms reset delay for timing compatibility with target processors. Evaluate the SC-70-3 package constraints for PCB layout space. Verify that the absence of a watchdog timer meets the system safety requirements.

Supervisors Part Context

This part belongs to the ADM1816 series of microprocessor reset circuits from Analog Devices. It shares the family's core supervision architecture but is distinguished by its specific 3.06 V threshold setting. The REEL7 suffix indicates tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Check Analog Devices datasheets for alternative ADM1816 variants with different thresholds if voltage levels change. Verify pin compatibility with other SC-70-3 supervisor ICs from different manufacturers before substitution.
